It was an interesting game, I can certainly see what you were going for. Unfortunately I got stuck after a very loud enemy at the red button and could not figure out how to progress. Technical issues like not being able to fullscreen the game, sounds that were way too loud and shooting not aiming where I would expect, my main point of criticism is that it didn't feel like I was racing around the track, especially when it came to the boost and the purple walls. Boost is too short to feel like a boost, it feels more like a power mode you activate right before purple wall to destroy it and it doesn't speed you up that much. Also missing purple wall just stops you dead in your tracks making you awkwardly reverse and then try again, removing any kind of momentum of sense of urgency. It's possible that technical difficulties made it feel worse than the game, but still good work on finishing the game!
I played this on stream, here is the highlight in case you find watching first playthough useful:
