Custom engines seem to be dying out, but at itch.io it's usually the games that I like the most. Everything is handmade according to your own needs. I like the game a lot, it has the charm of mid 90's racing games like Screamer 2 but despite the retro graphics everything is very detailed and the landscape is picturesque. The driving physics are impressive and as long as I don't leave the track I didn't find any glitches.
