Love the graphics style and that it supports as many players as the keyboard can handle. I could see myself hook this up to a makey makey ( https://makeymakey.com/ ) for a game night. Would need to have some kind of win condition though...
Here are some suggestions for future development:
Option 1: When a timer runs out the player with the highest current score wins.
Option 2: Configurable number of respawns. Last player standing wins.
For more control of the steering, the direction could switch everytime the key is pressed.
Would be nice to have the numeric keys work as well. If I hook up makey makeys it'd be good to use 1,2,3,4,5 for players 1-5.
Keep up the good work!
