Thanks for making this game, was a lot of fun to play and the graphics look very nice. Unfortunately, I think I got soft-locked at this spot though, as a door ate my key but did not open :(
Hey, super sorry for that, just pushed an update that fixed this one :x
Just had this happen too me to.
There should be an extra key, did you find it? And in the last patch that door should be not near the edge of the screen, so it doesnt it the key.
