Fun game, but needs some balancing. I really liked the music and art style of the game. RPG-type content was basically nonexistent, but I'm assuming that's because it's a demo. Maybe a future update could include some of those elements as they sound interesting.
As for the balancing, I only just had enough money for a ticket. Had bought more food or repaired more than the bare minimum to allow me to race, I wouldn't have been able to progress. Combine that with not being able to use boost (which you need to get ammo) and the manager taking all of your money, and the game becomes unnecessarily frustrating.
That said, I did enjoy my time with it and liked the "dusty cyberpunk" world you developed, instead of having just another dense, urban environment. People should definitely try it out for theirselves and I'm looking forward to future updates.
