That's weird, I'll look into it.
Supposedly it's an issue with a build compression setting causing the issue. I'll try to get a new build uploaded later today.
Does that happen when you run the game from your browser or is it only with the downloaded one?
It was my first time actually making pathfinding, so it's pretty unoptimized. I've got a few ideas on how I can speed it up, though. Thank you for playing my game!
