Thanks for the feedback!
I only actually made a build of the game right before I had to upload it and for some reason the physics changed in the transition from playing in the Unity editor to the standalone game. At that point I was so sleepy that changing anything would probably have made things worse. And time was running out anyways.
Absolutely agree on the game giving some feedback. I had planned to have a particle effect or something for the boost and yeah, I simply ran out of time with the sound. Since that's an area I know virtually nothing about it wouldn't have amounted to more than some bleeps and bloops anyways, since you can't use preexisting assets.
