Hello,
Here's my first game for Pico-8 and it's a Pole Position/Enduro/OutRun derivative. You might have already played it on my itch.io page.
Features:
I wrote something about it in my blog and if you have something to ask about it I will gladly answer here.
Edit: I'd like to mention I used the ord() function found here, it was a lifesaver.
Update: Now saves high score only when returning to title screen, would continuously write on disk otherwise (due to changes in 0.1.6)
