The sheep spinning when you climb was an extremely good choice. Also thank you so much for making a Game Boy game.
Did the block in the upper left corner of level 3 have a purpose?
I'm not sure where that sprite comes from, it could be junk in the memory, but I do have a pickup that spawns there. I removed the pickup since I couldn't get it to work before the end of the jam. I guess I left something there and the game is rendering whatever is in memory.
I'm planning to continue work on the game. When I get the pickup to work it should fix the problem.
Thanks for the feedback. Much appreciated!
