Someone posted this in a similar thread a few weeks ago and I loved it.

It's a roguelike RPG where the majority of rooms are logic puzzles filled with chests and mimics.
Mimics always lie, regular chests always tell the thruth.
Mimics insta-kill you when you open them, regular chests give you loot and xp.
