The game is really cool. The idea is very interesting and the principles of making the environnement move only when the player moves works very well with the concept. The design of the ennemies is also very cool for a jam. I could really see myself playing this game if it had more content. I also think that it would benefit to have more roguelike aspects.
I feel like that the ingredients needed for potion that kills ennemies should appear more, because the runs without damage potions are pretty frustrating. I feel like "effect" potions are only funny in combinations with damage potions.
Also i don't know if it's intended but it feels like running trought rooms until you find the ladder and just dodging ennemies is the better strategie, but i don't think it is the best way to experience the game and encourage the player to not use the main concept of the game, so i think the gameplay should prevent the player from using it. Maybe by making the ennemies drop more items, a boss every floor or a key system.
In a nutshell very good idea and good implementation of it. Could be a really good roguelike if developed !
