the new download version is pretty laggy. Idk if it's my computer that's bad, but I played the web version (couldn't import my account). Also, light hearted suggestion to make it so that you can toggle the checkpoint respawn.

when you get a checkpoint it saves your position, rotation and velocity so that if you go back to it you get that speed instead of no spee

Can you add a feature to import irl tracks into polytrack

Suggestion:
Different physics for different surfaces
(slippery for ice, less grip on desert/sand, etc)

Maybe make checkpoint order optional, or remove checkpoint order completely, and just make them a requirement to finish regardless of what order they are collected in. This would make finding the optimal route for a map interesting along with finding the lines.

Make your place on a leadorboard on a map visible without having to select that map. Your time on a map is visible from the menu, but imo place on leaderboard would be more useful

Hey! I get random lag spikes after hitting checkpoints. 

In the editor, when placing blocks by holding down the mouse, then using Z or C to move up or down, when there is a lag spike, it leaves gaps in walls and things when building...

i think you should put polytrack on steam because you can get money or choose not to and more people will get it and also you can set up steam workshop

its ok of you prefer not to say, but how much have you made off of itch.io dontions alone

Not too much of a bug, but apparently if you go 999,999,999 blocks out then make a map the car kind of collapses on itself:

Please add different times of day, I need a sunset and night time!!! It would enhance the atmosphere of community maps so much.
