Warning: the game is hard and you Will get frustrated. It is quite simmilar to Hotline Miami, You die fast and you restart fast. Spawn-Kill-Die-Repeat.
DEMO contains one level and a summary.
Consider changing difficulty if you find the game too frustraiting.
My best time beating this game is 33.437 seconds try to beat that time!
Demo Release!
