Pros:  Addictive gameplay,  Good replay value

Cons:  Some bugs (Timer will read 1:1 instead of 1:01 etc..., Restarting the game doesn't reset bullets)

Suggestions(One for each category that would of taken it to the next star):
Better difficulty curve (I think I could play forever etc...)
Bug fixes
Music / more sfx
Animations for the enemies.
Additional collectables for more points (possibly bonus drop when enemies collide instead of extra ammo)

Really fun game actually. Just needs some graphic improvements!

I'd love to read your feedback on mine :D!

What a fun game :D My highscore is 24. Ireally liked the enemy desings when gun holding aliens showed i laughed if we can hold a gun why they cant :D My only issue there is no background music.

Other than that great game loved it!
