I really like the textures and art. (The floor texture looks kinda fleshy - like it's a pile of bodies instead of stone - and the little sprites for the human characters are really cute in a way that contrasts all the monsters)
The gameplay also reminds me of Pokemon Mystery Dungeon, except without the Pokemon, but it's expanded to have things like the Spider Enemy acting twice and the tentacles burrowing underground so you can't see them, which is really cool.
Unfortunately, I was only able to get to level 2, which is partially on me not being great with harder games, but there were some really bad spawns (Fake Statue on a Note in a corridor, with the other Note I needed right beside it was probably The Worst) Which, I mean. Obviously that isn't easy to fix in a Game Jam Game(Especially because of the Procedural Generation! due to the time limit, but if you want to expand this game later on, I do believe that would be the first thing to fix.
All in all, pretty good game, if having some frustrating RNG at times.
