The game was developed by Frogteam Games and released on Steam June 10th, 2023. A port for the Nintendo Switch was released on January 12th, 2024.
Frogsong contains examples of the following tropes:
- Anti-Frustration Features: The game has several settings that can be adjusted, such as giving the ability to heal over time, or to not take damage at all, adjusting the speed at which the text appears, or giving hints at how to solve puzzles.
- Battle in the Center of the Mind: A variant with the final boss battle. The Snnikt gets into Chorus' mind in an attempt to control them, and they have to fight against it, but this manifests as them seeing the Snnikt as physically in the area while Basalt has become invisible, rather than Chorus being dragged into their own mind. Basalt later says that from her perspective, it looked like Chorus was hopping around and stabbing at nothing.
- Book Ends: The first boss ends with Basalt showing up at the last moment, much to Chorus' annoyance since they thought they could handle fighting the Slizer by themself. Near the end of the game, Basalt shows up again to save Chorus in the middle of the fight against Lithos, and this time they're much happier to see her, and she helps them in the fight's second phase.
- Broken Pedestal: Chorus wanted to join the Defense Guild after their home village of Tennsfall was under attack, and was saved by the Guild. They looked up to the Guild's leader Basalt in particular, only to be upset when she didn't believe they were capable of being a warrior. When they tell her later on why they wanted to join, she realises that the way she treated them must have ruined their impression of her. This later becomes a Rebuilt Pedestal when Basalt helps Chorus to defeat Lithos despite being skeptical of the Snnikt's existence and not liking what Chorus said to Rana, and allows them to join the Defense Guild in the end.
- Call a Rabbit a "Smeerp": The enemies are all different types of bugs, but they have different names. For example, a praying mantis is called a Slizer, a bee is called a Humming Devil, and a spider is called a Weblurker. Justified as the amphibians have different names for them than what humans call them.
- Cassandra Truth: After learning that the Snnikt is in fact real, Chorus tries to tell Rana about it, but she doesn't believe them, and they get into an argument that leads to Chorus getting banished.
- Chekhov's Gun:
- On the way to Boreala, Chorus passes a ruined building that is said to be an old dreamreading temple. Later in the game, they run off there and fall asleep, where they dream about being in a void-like area and see the Snnikt. While it's never made fully clear if Chorus would have dreamt about this no matter where they slept, it's likely that this is what allowed the Snnikt to find out about Chorus and be able to get into their mind later on.
- A metal tower (most likely a radio tower) can be seen from the hill where Bufo's house is, and when he and Chorus are looking at it, it gets struck by lightning. Chorus ends up defeating the Snnikt by climbing to the top of the tower and letting lightning strike the Sunblade.
- The Corrupter: The Snnikt is implied to have done this to Lithos, preying on his desire for power and immortality in order to cause destruction. It soon decides to do the same to Chorus, trying to convince them to get back at those who wronged them, but they refuse.
- Degraded Boss: The first boss battle is against a large praying mantis, called a Slizer. You encounter one again in the final area, and although it's the only other one you see and it's in a room by itself, there is no fanfare around it and it goes down much more easily.
- Dirty Coward: The two frogs that work for Lithos plan on scaring the people of Boreala by unleashing a Slizer on the village, but when it breaks free, they run off and blame it on Chorus, who stumbled upon their plan. Later on, they block the way to where Lithos is and claim that they will do everything they can to stop Chorus from reaching him, only to immediately run away as soon as the wall of rocks they've built around themselves is knocked down, which only takes one or two hits.
- Disney Villain Death: When Lithos is defeated, he starts going on about how he can't die as long as he serves the Snnikt, only to start coughing from the illness he claimed to have, causing him to lose his balance and fall from the tower. The Snnikt then tries to get Chorus to accept its power, having taken more of an interest in them, and it's implied that it might have been responsible for Lithos' illness returning.
- Door to Before: A few of the areas have hidden paths that act as shortcuts, although there's nothing blocking them from the other side so it's possible to skip several parts of the area by using them. However, the final area does have a shortcut that is blocked from the other side, requiring you to take the long way and pull a lever to make the path available.
- Eldritch Abomination: The Snnikt is a shadow-like creature with glowing, diamond-shaped, red eyes. It can shapeshift into many things, and make darkness appear everywhere, and its default form appears to be a giant deer with arms and hands for antlers.
- Eldritch Location: After Bufo's funeral, Chorus runs away to an old dreamreading temple and has a dream in some kind of void-like area with strange, dark creatures floating around. Right before waking up, they encounter a larger creature with red eyes, and realise that it's the Snnikt. It's later implied that this was the Snikkt's first attempt at reaching out to Chorus, so it could try to corrupt them.
- Evil Cannot Comprehend Good: The Snnikt doesn't understand why Chorus doesn't want to accept its power despite being looked down on by most people, believing that they would want to get revenge on everyone, and brushes off their refusal as an act of cowardice.
- Headgear Headstone: While Bufo's body is sent into the water after he dies, there is a gravestone near his house which has his hat in front of it.
- Jerkass Realization: Basalt realises that she was too hard on Chorus after they risk their life to get some honey from a Humming Devil nest in the hopes of curing Bufo's illness, and after they tell her that she and the rest of the Defense Guild once saved their old village, which is why they wanted to join in the first place.
- The Marvelous Deer: The Snnikt's default form appears to be in the shape of a giant deer whose antlers resemble arms and hands.
- Playable Epilogue: After the ending scene and the credits, you're able to keep playing and talk to everyone again, as well as finish any achievements you missed.
- Plot-Mandated Friendship Failure: Chorus and Rana have a falling out after Rana becomes the new Elder and Chorus finds out that the Snnikt is real and tries to warn her about it, only for her to not believe them. The argument escalates into Chorus telling her that she is nothing like the late Elder Bufo, leading to her banishing them. They reconcile in the ending scene, and apologise to each other in the epilogue.
- Queer Establishing Moment:
- When Chorus introduces themself to the Defense Guild, they explicitly say that they're nonbinary and use they/them pronouns.
- It's easy to miss, but the frog couple that gives you the pie at the beginning are both male.
- It's hinted a few times throughout the game that Rana and Basalt have feelings for each other. This is confirmed in the epilogue, where Rana says that she asked Basalt to "be [her] girlfriend", and they're now dating.
- Real After All: The Snnikt is initially believed to just be a myth made up by warriors during a past war in order to scare their enemies, and it's believed that Lithos is doing the same thing in order to expand his empire. But then Chorus has a dream while sleeping in an old dreamreading temple where they see the Snnikt and learn that it's real, and encounters it at the end of the game.
- Surprisingly Realistic Outcome: After arriving at Boreala, Chorus receives some pie from one of the villagers. Make it to the epilogue without ever eating it, and you'll find that it has gone bad, as several days have passed by this point.
- Treetop Town: Tennsfall is a village built up in the trees. It makes sense since most of its population are smaller frogs, with Chorus being explicitly said to be a tree frog.
- Weird Sun: Partway through Chapter 5, the sky turns red and the sun appears to be eclipsed with a red glow around it. It's unclear if this is a normal eclipse or not due to the aforementioned redness, but it does seem to tie in with Lithos wanting to summon the Snnikt, and the sun and sky go back to normal shortly after it's defeated.
- Wham Shot: The Swamp of Glune has a few when you get to the area where the Sunblade is. Firstly, if you go as far west as you can, you'll find that the house shown on the map is absolutely huge, and going inside will lead to a giant desk with jars on it that appear to contain some dead frogs. Back outside, going further north will lead to a giant tombstone with the name "Annora Gallagher" on it, revealing that the legend of Anaura that some of the frogs believe in and created a religion around was based on a human being. To a lesser extent, it's also shown that the Sunblade is actually the tip of a fountain pen.
- Zero-Effort Boss: The battle against the two frogs working for Lithos ends up being this. They block the way while surrounded by a wall of rocks, saying that they will stop you from reaching Lithos and putting a stop to his plans... Then stay right where they are, only throwing stones at you, and both run away the moment you knock down their wall, which is very easily done.
