Thanks for playing and the feedback! Yeah, either Daze or Poison can get overpowered - both together are ridiculous. But, I like to think that if the final boss gets a turn, you're not deck-building right :D.
For the fire area, the exit I think people are looking for is to the left right after you go through a door, and the very low contrast visual style I did for the fire area means you don't even notice the hallway there unless you're really looking for it, so you just don't look to the left to see it. For a post-jam update, I've moved that particular one so it's visible when you enter the room on your way out (though the rest of the one-way doors are staying ^_^).
Glad you liked the visuals, it was fun trying something different!
