Very great job guys! One of my favorite games of the jam! It felt "too detailed" to me to match the GameBoy soul. I was also a bit frustrated to see thin platforms that still have full tile collision. But these are the only reproaches.
I had a bug in world 2-2 where I wasn't able to place tiles (they instantly moved to the one on the right), and even switching modes/moving the player didn't do. But, well, game jams :)
