I really like all of the colors you put into this game. I realize its still a demo, but maybe you could add more power-ups, and eventually have a sleek looking interface (I suggest picking a new font to use too). Also, it will probably get boring after a while, so you might want to consider making it a little harder.
Looking forward to the full version!
It looked so pretty! You need to add more power-ups and enemies. You could also add a subtle background, anything too strong would ruin the look. Looks like it's going to be great when it's finished!
Graphics yaye, gameplay naye.
Your game has a very unique look and graphics. I liked that.
However, you need to strongly improve the gameplay, say, create levels, backgrounds, a weapon upgrade system or something like that.
The game, as it is right now, is not much more than an Asteroids-clone.
