Haha, awesome :D thanks for playing!
Regarding the walls thing, we wanted to telegraph it to the player more for sure, but the whole level-design part didnt really come together until the last part of the jam, and while I was plugging away trying to code stuff, my wife was having her first-ever go at level designing xD.. But after the jam, who knows, maybe we'll pick this back up, and we'd definitely look at improving aspects such as that.
