I love the art style and the consept of controlling 2 characters who need to work together works well. There were a few issues that im sure you would have fixed if you had more time. The movment felt slightly jerky and the player collisions somtimes got stuck inside things (and i couldnt manually restart). The energy went down a little to fast for me and the levels were a bit hard lol (mabie skill issue). Also energy went into the negitves.
Cool game consept and with some polishing it would be even more fun. Good work :)
