The first level was easy enough. But after that I got stuck. I understand I'm supposed to go somewhere and then get back to where I started. Maybe the starting location could be highlighted somehow to make that more obvious. It could have used more sound, but I like the visuals high-contrast visuals (and the not-so-distracting moving background behind the rectangles that the levels are in). And it looks like you finished almost two days early, so there's that too.
