glad you find our game fun, thanks for the organised feedback and great suggestions.
i was supposed to add a lot of variation and better enemies by the end but i had some work that needed to be done, because of that i was unable to work on this, making the game limited to 5 floors was a last minute change that's why it feels longer and boring right now as none of us had time to playtest the end, ironically the best way to avoid damage right now is to not move because of how enemies are coded :p
