Melolune is an indie RPG game developed by Laura Shigihara, who's known for composing the music for Plants vs. Zombies. The game has not been released yet, though a playable beta is out, which is free to download here.
This game provides examples of:
And Your Reward Is Clothes: This game loves this trope! As you progress, your Hammerspace slowly but surely becomes a wardrobe. Though at least, clothes also provide some protection in battles.
Ambiguously Gay: There is a guy in Debonet who is really impressed by Achaius' blue eyes.
Animal Talk: You thought you can't start conversations with animals... wrong! Some of them will be happy to talk to you!
Background Magic Field: "In my world, there are silent melodies all around us... If you listen carefully, you can catch them, and turn them into a song... Some of us can turn them into more than that... We call these fragments: Melolune."
Berserk Button: A sociopathic Ciro soldier successfully triggers this on Achaius. "How about this. After we poison them, I'll let you bury their dead bodies.", uttered the Soldier, referring to the entire population of Leeble Village... no surprise he got a kick on the ass.
But Thou Must: Several conversations offer you only one option to progress. The other option either does nothing (which is good if you'd like to stay and explore without making progress) or makes the character repeat some of their previous sentences.
Changing Clothes Is a Free Action: You are free to change your clothes, though you won't see any change on your characters, for they don't have various sprites for various clothes. Still you can see what are your characters wearing in the "Equip" menu.
Everything Talks: Besides animals, wooden signs also talk sometimes... and who knows what other stuff?
Fictionary: The Ciroan language. Word of God says there are syllabic similarities to both Latin and Japanese. Moreover, the Ciroan songs on the Melolune OST ("Melolune" and "Carya de Mio") do have meanings. But this is all we know: actual meanings of specific words, phrases, lyrics are not revealed.
Fan Work: Fan work for Melolune is pretty much encouraged and appreciated. Sometimes the creator announces contests to motivate fans to create fan work. Here is an example. If Laura really loves your fan work, it might end up on her websites, in her forum avatars/signatures, or even in the game, as honor.
Find the Cure: Achaius gets infected in Debonet and can only be cured by Dolby's melons.
Dolby's cave: you can't move a pixel without being attacked, and so you must sweep all the paths over and over again as you come back and forth.
From Bad to Worse: Though some Leebles express their worries about the increasing number of Ciro soldiers camping near the village, it's not really a problem as long as the soldiers are neutral. But it turns out they intend to destroy Leeble Village.
Game-Breaking Bug: Would you like to switch from windowed mode to full-screen or vica-versa? Press F12! Great, it works! And now you're back in the main menu... without a "resume" option... and you realize that you've just lost all the progress you've made since the last save. The only option is to reload your latest saved game, then.
Game Maker: The game is being developed with RPG Maker.
Hammerspace: The player is able to carry an infinite number of items of various sizes. For example, Suby's enormeous glider perfectly fits in Achaius' pocket along with clothes, items, and the arsenal.
Happily Adopted: Achaius and Dominic don't mind living in the Leeble Village amongst very caring Leebles.
Heroic BSOD: Achaius, Dominic, and Aero are pretty much freaked out after a Ciro soldier attacks Mani.
Musical Gameplay: The very beginning of the game, when you need to put Melolunes on pedestals. When you place a Melolune on a pedestal, a music sample starts to play. When you remove it, the sample stops being played. This also happens in a cave.
No Name Given: "Big sister." Despite the creator was caring a lot to name the vast majority of the characters (even minor ones), this pretty girl is still left without a name.
Can you imagine that Achaius' family really didn't name her? Probably she does have a name, it's just not revealed.
Sequence Breaking: Due to the game's beta state, many possibilities haven't been tested and fixed yet, so you can easily provoke some odd phenomenons:
No matter how long journey have you already made, you can easily go back to Leeble Village anytime... where the Leebles act like you have never left...
There is an inn, where a woman suggests you to go out and talk to a wooden sign (which again, works!) and sleep there. After you did so, just go back to the inn, and the woman will continue to suggest you the same, despite it's already morning.
