The good things:
+ Nice graphics
This could be better:
- add Music plz
- more contrast for the text
- Powerups, Aliens and High-Scores (and maybe a story)
(maybe a store with upgradable stats)
And I found some Bugs:
* If you shoot behind you (while flying in one direction) the projectiles don't fly so fast like normal.
* The rate of fire is not constant.
