I like that all the "upgrades" have meaningful pros and cons to make you weigh the risk
Main two pieces of feedback are:
- There's very little contrast between the different sprites and tiles, so it's a bit hard to clearly make out some of the traps
- The camera always being exactly centered on the player makes it hard to see ahead or keep track of things in the room
Both of those can sometimes make some of the traps feel unfair when you get hit because you just can't see them
