Great game, in my opinion probably the best game for the Ludum Dare 23. The game was short, but no-one can actually blame you for that, considering the short amount of time you had for creating this. The art was really cool and over-all was the game extremely enjoyable and very inspiring.
Furthermore was the art pretty decent, I love pixel-art i general, so that's a plus. My only issue would be the level design, which wasn't exactly bad, just not outstanding.
Anyways, great job, you really pulled off something great in such a short amount of time.
