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.

here is a suggestion 

Can you make a feature like the structure block in minecraft?like copy pasting a big build cause it takes a while to make an exact replica of a build

Collisions feel kinda bugged for me. Mostly the track edges can fling the car all over the place which is confusing. Also you can phase into the scenery mountains if you go fast enough. (I play this game too much)

Release the WebGL/HTML build so I can host PolyTrack on my own site.  It’d be super helpful since my school blocks the main URL.

is it possible to make a way to report in game usernames? I am seeing user names that are inappropriate or mean sometimes

This seems like a crazy suggestion. But anyway, what if there was a single block eraser? like how eraser deletes the entire piece, a single block eraser erases a section of the block. Even if this works only with the full 4x4 blocks, that would be cool. As well as this, why does the FPS display cover up the bottom checkpoint meter? Also, small check, is the top lifted part of the car a cockpit, or an extra air intake?
