YOOOO! This was fun!
Here's my notes:
+ The design is smart, with the combo of the time-decrease each lap and the increasing chaos of the looping ghosts you get some good longevity out of a tight game like this. The leaderboard is also a nice touch - and DANG are some people playing the heck out of this!
+ From a UX/Bugs standpoint I had a few things stand-out:
1) I got turned around at one point but didn't know it, so ended up losing that round. Some kind of big ol' "WRONG WAY" on screen would be great to avoid that, since there's no benefit to the player going backward.
2) It took me a bit to realize that the power-ups were the white things, since the first two times I saw them it was the lightning bolt which looked like some spikes I needed to dodge. Maybe a more mario-karty vibe for those, where they're less specific and just nice call-out element that turns into whatever would be more readable.
3) The sensitivity took me some time to get used to, but the slider on the main menu helped a lot with that!
Overall really solid, and a smart approach on the art with the neon aesthetic since that avoids having to texture stuff! Love economy on the art side
