Nice concept!
I like that there is some replayability in the game, and it won't be always the same things to do each time you play. It makes it way less painful to lose!
Also, I really like the aesthetic! The art is really nice and the music fit the action very well!
The challenges are all interesting and fun, except for the one with the walls and numbered buttons, I never understood how to go through the walls!
Also, the challenge with the objects to place in the correct spots can be a bit frustrating when the object don't go in the right direction.
Last thing, at first I did not understand that I needed to get a certain number to win, and I lost by clearing every room. Maybe you could make the number required a bit more obvious at the start of the game.
Good game overall, well done :)
