woooow more invader zim? Really? Why cant we finally get a AAA game that gamers actually deserve? What the frick?

To many problems.

Is that a pokemon I notice in the background? Anyway you have a good idea here, as most do, but you didint make the game very well. You simply made one background and three sets of enemies. When you beat or lost to the final wave nothing happend. Which is kinda dumb since there should be a cutscene or "you acmoplished this!!!" Same thing for when you die, there should be a "you died :(" message instead of directley to the menu. The graphics were pretty poor as 5 sprites in one game isnt very good or creative. Try better next time, put more effort into it.

Too short, technical issues

3 waves of enemies, and only 1 background/level graphic and animation, and its wasn't even really that strong. The projectiles from the enemies actually didn't fall from the enemies I noticed, which made it seem kind of cheap, because it meant you always had the same number of projectiles to dodge even though fewer enemies may be on screen. The gun fired a bit too fast, making it really easy to blast away the waves of enemies quickly. So the game being short and being too easy just made for a very unsatisfying experience.

needs work

invaders fall to fast.

Projectiles (yours and enemies) need to be slower, at least just enemies.

Use a healthbar instead of lives

Music rocked

great.

For the person before me, YOU'RE SUPPOSED TO TAP THE BUTTON, NOT HOLD IT! Also, I think the classic one has shields, too.
