Cool Atari-style shooter. The turret system is innovative, and I like how there are different hazards above and below.
That said, the controls are a bit too fiddly. I would have used a single button to detach from either turret (just as we have a single button to control either turret), and it should not overlap with a movement key.
Also, at some point the turrets just stopped shooting. Perhaps I ran out of ammo, but I couldn't determine that
The sound effects are effective and thematic, but I think the volume is too high.
