Thank you for playing! It's true that it's kinda easy in the sense that you can just simply click random floors since there's no concrete objectives at the moment, it's something I can think about :D And your comments about shop indicators is also the same as other people have pointed out which is that the most important info of the game is actually the smallest thing you can see on the screen. It's something I have to improve as well.
I have to look into the last part you mentioned as well to see if it's just a funny coincidence or it's a bug, thank you for commenting on it!
