That was actually EXTREMELY fun! I can't believe it took me this long to find this gem!!
In the end it said you wanted feedback but honestly I don't have much to give, the game works perfectly for what it's trying to be! I found lvls 5 and 9 to be quite hard compared to the others but not close to being too difficult to finish.
The music was freakin great too! honestly this whole thing is a delight!
