Pretty great idea going on here! The control placement was a little bit awkward (i find arrow keys awkward in general, and left ctrl really threw me for a loop), but it was pretty quick to get used to, and didn't affect the gameplay at all! I really appreciated how large the radius to reattach to the ball was, I'm not good at controlling my vehicle in these kinds of games, so that was a huge relief! I found it a little tough to hit enemies consistently, unless i was spinning in a circle, but again, I'm bad with this type of game, so it could partially be my skill level.
Overall, really good submission, great job!
