Best feature to ad would be that when you finish a level there is a "next level" button instead of going back to the level select screen :)
good game
4/5
Fun game, but the collision radius of the ship is bigger than the icon, an enemy laser can hit you and be off by 10~15 pixels and it still registers as a hit.
When i died it didnt actualy display my score (around 2k), but its a good first game, you should make it so that the food your collecting is a different colour, and maybe a pause button (if there was one i didnt notice it :P)
