This was a fun game I made a few years ago. Emphasis on was though. I have recently discovered that the controls for this game are really slow and unreactive. I will probably change this in the future; maybe I will make it feel a lot like those older style shooter games.
Resources I used to make the game:
Controls are the WASD keys and SPACE to shoot. It should also support controller input, though I'm not certain that will work on the web. Alternatively, you can hold right click on your mouse to have the ship follow that and hold left click to fire.
