WASD to move. M to mute sound and U to unmute. Shoot bullets (bullets...bombs...nvm) with the Space bar. Shoot the monsters to get points. Don't get hit by the monsters. That's all.
Elements and most of the code from Roboto Coding Academy. I'm gonna make my own project soon. I need some ideas though, comment down below what type of game (or animation) should I make. The new game won't be out soon because of some limits.
