Please, make it mouse based, and make sure the random asteroid generator makes it so that you can always get through a wall. Also upgrade your collision detection.
wait. wtf? 1/5, and flagged for not being a game worth calling a game. Since "removing the spam" is the point of the game, flagging it is the best way to play this game.
The accelaration doesn't work that well, but ok. 2/5, 3/5 if you mix the music and make the tack move a little faster with higher accelaration. Additional points will only be given if you make massive changes such as making a different concept, You can only do so much with up and down before it's boring.
Pause doesn't pause it. Also there's a level that has a purple block on your spawn point that kills you, I suppose this is the end. When you die from the red block, you should be healed for next life. Nevertheless, it is pretty well done, if unoriginal, so I'll give you a 3.
I'm guessing its an april fools joke, and the game actually never loads. Therefore, I shall flag it and give it a 1, since april fool's day is long past and this should not be here.
Too slow, you should be slightly faster or slower than the zombies. In fact, you should make everything faster, it feels boring waiting for pizza guy to go half the stage.
