Far lower rating than it deserved simply because of one thing- this caters to those with mouses. I cannot even play properly and there is no option to change the controls. I hope this can be added in the future.

One of my favorite flash games of all-time.
I'm bummed, though, because it won't load.
Worked fine on Armor Games but had some lag issues there (which always seems to be the case at that site).
Really too bad. I do, genuinely, LOVE this game.

Great game! At least 1 full hour of challenging fun. Although it didn't give much in terms of story (endless, literally) so we never find out about the purge, it gives back with authentic gameplay.

I have nothing to say other than the system of advancement could be better (based on time and not on pixels collected/level).

Got 4,532,965 on my last run. This was legit, and anyone trying to go over a million should NEVER EVER upgrade "pixel" and "magnet" (avoid at all costs gathering pixels because when you get stronger, the enemies get stronger) and try not to upgrade "points" either because they only affect "kill points" and not "chain points". Since the rule of thumb is to do enormous chains (kills without being hit) the point upgrades become far useless than the damage ones.
