I held the spin button for a second, landed on my head and spinned forever. It was funny though, good job with what you got to work in your time!

Turn speed is extremely high (due to high framerate?)

I'm guessing this is due to the lack of time, but tidying up the controls and adding SFX to movement and shooting would help game feel and user retention. Anyhow, I found my fun with it, my machine turned upside down, and when I pressed down and to the left, it started rotating and it elevated from the ground.

Cool little project, but if you made the scope smaller, and focused on just the tank exploring the area, probably it would be a good cozy game.
