Quite simple and fun. I held out about 4 minutes :D Gets incredibly hard after 3 or so. Maybe a health bar on enemies might be good. This way, the player can understand which ones are the hardest and have some strategy. Ghosting was a nice touch (:
Would you spare a few minutes to check out my game as well? It also offers a ghosting feature as of Lebel 5.
