Sorry to hear! I didn't really notice that while developing it, but now I see it, especially while holding the brake button. I've looked into it; the angular_velocity of the spaceship was incrementing even with rotation locked in because I used apply_torque and did not clear it when a movement button was not being held or a maximum rotation was reached.
I'll upload a new version after the game jam ends fixing this issue and some others. Hopefully you'll be willing to give it another shot afterward! Thanks for playing either way!
