I had the same issue with the super-fast ships, but the movement on my ship actually felt pretty satisfying all sped up. It's hard to rate given the crazy framerate/physics, but I had fun zipping around for a bit.
Yea. It's a simple bug. I just had to change 2 lines of code to fix it. Too bad i didnt test it enough while i could still submit a non-bugged version :/
