A notable game mechanic is that while Sorina (usually) starts as a human, she suffers from vampirism and will turn over time. Once this happens, all enemy vampires become friendly, but the many other human explorers won't take kindly to your change...
Vampirism also comes with a host of other advantages, such as increased strength and the ability to hide in shadows, but also with disadvantages such as illiteracy, the inability to use weapons or magic, and weakness to water and sunlight. Changing back also requires valuable Soul Elixirs, so switching between the two forms isn't something to do casually.
The game also simplifies many aspects of Roguelikes. For example, all potions are unidentified at first, but you are shown three possible effects that they might have. Also, there is no equipment management: all equipment is either objectively better or worse than your current one, and if it's worse you automatically sell it, instantly gaining money.
Tropes found in the Golden Krone Hotel:
- Blackout Basement:
- You can invoke this trope by putting out torches, which is handy as a vampire with night vision.
- The River completely lacks any light source, which makes it tricky to navigate as a human. And it's full of vampire-hurting water, so you can't just use their night vision. You'll have to either work through the darkness, or have a magical source of light (either a spell, or a potion).
- Bomb-Throwing Anarchists: The Goblin Anarchists, who hold sticks of dynamite and explode upon death. If you're a human, you can shoot them or cast magic. If you're not, you need to take the blast.
- Fur Against Fang: Downplayed, but there is a potion of Luna that lets you temporarily become a werewolf, which both humans and vampires are hostile to.
- Hell Hotel: The game's setting is a vampire-infested hotel. Some NPCs mention that they've slept in sewers nicer than it.
- Humans Are Warriors: Their krone is made from the steel of a weapon, contrasting the vampires' golden krone.
- Interface Screw: The Delusion status effect changes the appearance of everything. The Pharmacopeia branch permanently applies this effect as long as you remain in it, making normal enemies indistinguishable from the boss.
- Meaningful Name: "Arobase" is the French name for the '@' symbol which is typically used to represent the player in ASCII-based roguelikes.
- Our Vampires Are Different: They are illiterate, have deformed claws for hands (which prevents them from holding swords or guns), and are harmed by water in addition to sunlight.
- Red Filter of Doom: The screen becomes increasingly red as your vampirism meter fills up. Once it's full it goes away.
- Vampires Are Rich: One random NPC conversation mentions that the vampires' krone is made of gold, contrasting with the humans' [steel krone made from a smelted weapon, which reflects the values of each group.
- Wizard Needs Food Badly: Present in two different ways, depending on your form. As a human, you will starve to death unless you use food potions. As a vampire, your health slowly falls, and can only be restored by feeding on blood. Blood appears when you attack enemies, but can also be found in convenient bottles.
