I really like the game, having to manage the steps you take is really interesting. The characters are nice, also with nice artworks and I like how you get introduced to the game by some characters in the game. I also find it interesting that you have to manage your countdown to count down the floors.
For me the only issue is that since you don't know where to go to travel down the floors, you end up "wasting" a lot of steps and since the levels are always different you can't "master" the best route. I think that maybe adding an undo option (even for just a couple of steps) could be really helpful.
Love Godot as an engine, we always use it also for our games!
