Use the arrow keys to move. The bullet is a little bit glitchy, but at the time, there's nothing much I can do about that. Update: I have fixed the problem and the game can now function correctly. 6/7/21 (The bullet moves faster than the rocket, so if it goes off the map, just press space to fire it and bring it back.)
A pretty easy code, but yet it makes for a pretty fun game if you just want a simple game or, want a simple template to remix and change a little to make it your own!
