Nice game with a interesting twist. However, I thought the main mechanic feel a bit too difficult to get access to, since the time window you get for activating the boost is very short, unless you are just driving in lockstep with your ghost, but it seems very unlikely. The car physics could also be improved a bit to make driving feels better or more realistic. For example I think the turn rate for the car is too fast and not very realistic.

Thanks for the feedback, it's interesting that you think the driving should be more realistic. I think most people would find the turn rate is already quite low compared to something like Super Mario Kart or F-Zero (which this game takes some inspiration from)! But it's true, I would have liked to actually make it more realistic like you say, if I had time.
