Thank you so much KV_Kingdom!
I definitely agree with the size of the maps being too large (specially considering this is a jam game) and the game doesn't feel rewarding in terms of gameplay, since it's all about rng and no skill is really involved (maybe deciding what items to preserve, although since some of the might fail, I guess sometimes it's not possible to do that).
Regarding the elevator, there was a message saying "Defeat Mason", but I reckon that's still a bit too vague and there should have been an additional indicator that you must deplete Mason's life.
