I can't beat it... also, i beat the green cannon, thinking ''Yay! It's over!'' and then ''A snake-OMGWTFBBQ?! Besides that, this game is really fun ( so fun that i now hate it) and someone should do it with othe songs too. Now i will get my hard badge... i think.
I was trying to get the ''kill 5 grays'' award when the gray formed a void eater right next to me... luckily i had reactive armor, but a sec later a horror formed and chased me around before killing me... on small.
