The framerate is pretty choppy and the kart is really slippery to control. It could also use more customization options for hats and cosmetics since there's only three of those. The level design for the "complete 3 laps" level isn't really that challenging and it looks like it was made in a level editor. There's a glitch where if you land on the curb of the track when driving off of a ledge, you get stuck for the rest of the game time. I will say though that the drifting works fine, but that's about it. It's best to structure the game from scratch rather than from a microgame since this is usually what can happen. I've come across some games using this engine structuring before and they didn't turn out particularly good. I can respect that you and your friends worked together to at least put the effort into making a game though.
