Neat game! Pretty short, but it's a nice vertical slice imo. I did find it a bit hard to judge where the ship is at in 3D space, and where you're actually aiming at. Could be a side effect of the retro pixel look. I didn't seem to crash into anything but I found it quite difficult to feel where I was.
Also chiming in on the Ctrl+W trap for web games, I didn't fall for it this time :D
Anyway, good job!
