From what I saw, this was a really neat game, especially as a first time in Unity for a game jam. I really liked the visuals of the environment and how that shifted between floors, though it seemed like the performance was a little slower for it.
I also quite liked the design for the weapon, it was a creative way to vary gameplay in the spirit of chaos. I do love some customization in weapons, and while the player doesn't have full control, it was a very strong concept!
Great work!
