The attention to detail is insane, and the game feels very polished as a result. The graphics are gorgeous (although the characters and karts feel like they could use more polygons, and possibly a graphical option to control them alongside the frame rate). However, I have a few issues with the gameplay, and I did notice a couple of oversights.
- While I'd rather play with a gamepad, there should have been an option or quick-press in order to swap between the two. If I wanted to use the keyboard, that would have meant unplugging the gamepad which isn't ideal.
- There's no analog steering with the gamepad, which makes steering kind of awkward. I know Mario Kart isn't about apexes and shortest/straightest lines, but steering all-or-nothing doesn't feel right.
- Some kart noises would be nice. The game felt a bit too quiet, even with the nice music.
- I hit a booster pad and didn't turn well enough before I was flung off the road. Upon being dropped off, the boost continued.
- It seems you don't have to drive through the actual finish gate in order for a lap to be counted. This means that (especially with a few mushrooms) you can take a major shortcut on some of the tracks, like Donut Hills.
- The rear wheels are turning along with the front. This wouldn't make a kart turn, but strafe.
- The kart should angle with the slopes so it looks like they're actually driving up them instead of climbing.
- The tracks feel really narrow. Given the speed you move and the tight turns at times, I spend a lot of time either off the track, or bumping into obstacles and competitors. There's little room to maneuver and it makes the karts feel gigantic.
- Drifting doesn't feel right at all. I either make a hard turn in the direction I want to drift and go veering off the track, or I try to compensate for the drift's direction and end up going the complete opposite way I intended to. When a drift is "successful", it just felt like a regular turn and I didn't seem to get anything out of it (besides a speed boost where applicable).
