NOTE::: to go to the next level press the red arrow in the bottom right corner. u do not have to kill everyone to go to it but then theres no point to the game. All you do is shoot people, theres no ryhme or reason its just fun blowin peoples heads off. There are 3 enemies on each level. Enjoy. BTW i know theres a glitch that sometimes the people stay dead when you go t the next level, im workin on it but i can't figure it out, so if anyone knows how to fix it let me know.
