Use WASD or the arrow keys to move. Press the space bar key to kill all monsters if you have a power up. The blue power-up makes your bullet go faster. The yellow power-up makes you have one "kill all monster" power up. The orange power-up shoots two bullets and one of the two bounce. The white power-up (predicting eye) predicts where the power-up will be before it comes. These monsters have artificial intelligence to pick whether to kill you or destroy the power up! Shoot the bomb or you will die.
Please don't complain that the bullets are too slow in the beginning. Sometimes mobs suddenly appear so watch out! Try to survive the longest! Sorry it has a lot of gliches
