This is an amazing game! I like the concept to use the rollers to play around, it's been a while since the last time I play some sort of free-to-explore racing (? I don't know what umbrella term I should use here) game. Rollering around is so much fun in this game, and there's some visible checkpoint enemy that we need to hit that makes it even better than just roaming aimlessly.
The music also set the atmosphere of the game greatly! May I know where I can find the music that you use in the game, especially the one that's played in the early stages? I want to have them on my music playlist. XD
By the way, I streamed the game below around minute 173 in case anyone wants to watch it. Not that I got any good score though. XD
