Hi! I saw you left a rating on the game along with this feedback, thanks for that!
- Yes uzi is supposed to only shoot backwards.
- Cleansing is the second rarest material in the game and designed to be very strong. Min-maxing with it is intended, game should still remain challenging on harder difficulties even if u do so.
- I saw you mentioned a revive bug in your rating. It was likely caused by being able to take damage and die during the revive process, oops... Hopefully I fixed it now.
Thanks again for the feedback and enjoy playing!
