Well, game is short and controls are fine. I completed some levels without touching the green blocks at all because I didn't know I could toggle them hahaha. I found out in the last level :(
"World map" level should update door sprites when you have completed each level though.
And it seems there's no.. Game Over after you complete everything, isn't it?
I love it when jam organizers also do an entry. Good work Asset Jesus, keep 'em coming.
