Too bad there's only one level, it makes it hard to see what the other puzzles would like because it looks promising =/ (Maybe you could upload a post jam version with you level loader fixed ? I know how frustrating these things get when you have to fix them at the last minute ! )
The Music is really catchy and fits well with the game.
The graphics are okay, by that I mean that most of the sprites looks super cute but the world doesn't really. I also did not understand if the different color tiles serve other purpose than just a decorating one.
Also, and I would have preferred to test other levels of the game before giving my opinion on this, I Do not really find the control scheme intuitive. I would have preferred a direct mapping between the arrow pressed and the direction the robot will move toward. But depending on how you exploit it, it could also be totally valid to use the present control scheme.
And in any case, congratulations on submitting ( an such a cute game ) on you first ludum dare :)
