Erm who's JBAE?
pretty good job, I like the art and the lighting is nice. The whole game is easy enough to play and the puzzles are cool.
You seem to be lacking a back button on your How To Play screen though, that was odd. The control system felt... off but it was ok. I think increasing the hit boxes for the control arrows would help that. And I would also say don't let the lighting affect the visibility of the controls!
Other than that good job!
