It's hard to figure out what is going on, going up the stairs leads to death in a couple screens, so does going down. Maybe that's intentional but you have pretty long meters for this to be done in only 2-3 loops.
There is a bottom to the staircase but that is kind of unclear. I definitely should have done more playtesting and added a tutorial or some HUD to display the floor count, my bad. I hope you still enjoyed the game! Thank you for the feedback!
