In fast hands, You need Fast hands. I think that's fairly obvious... Mouse to move click to shoot. You can only shoot in the direction you are looking. To shoot the enemy you need to actually be looking at it.
I made all art work, all code, and there is no music. NO REMIXES! I ask this because I make all games with a vibe. If you change anything, It ruins the vibe. I would hate this project to have health bars for example, because that would take away the risk-taking vibe. Ya liked this one? Try another game by me!
