You had me a "Tiger Mutant Playing Extreme Hoverboard"
Good mechanics, they maybe feel a bit slow to me for a racing game, especially when I was grinding on the rail. Overall though, I think the main limitation of this game was how uninteresting the map was. Don't get me wrong, the environment is incredible, but the actual track I was racing on was pretty bland and devoid of anything interesting aside from the loop de loop and the spiral. I definitely think that taking inspiration from the best parts of something like Mario Kart or the like wouldn't hurt if you wanted to improve on that.
Great job overall, it looks really well done!
