Had fun with this, I'm a big racing game guy and this has a good feel to it. I think the game has a little bit of an identity crisis, to me the driving feels like a pretty casual arcade game but you're trying to do a full gearbox simulation which I don't think aligns. I had way more fun when I turned off the manual mode.
Anyways I uploaded all my gameplay to youtube. I ramble a lot and I'm pretty cringe, but I know seeing video can help understand how players interact with your game. So if it's helpful, cool. If not no need to watch them.
