Use WASD to maneuver your rocketship. Conserve Fuel (F) by Gliding. Press or Hold Down to fire your laser ahead of you. Hold for 10 seconds to activate a laser, which does more damage but consumes a lot of fuel.
The coding here is kind of messy. I'm going to have to re-write it almost completely if I want to make the actual game, with more levels (I'm very lazy, so I probably won't). Some changes for the finished version: New Weapons, and a screen to equip them on A scrolling engine More Levels More Enemies Just a bunch more stuff tbh
