Cool game, it gets really frantic but the rings and shields are visually distinct enough from the traffic to avoid situation where you get caught out by not know which lane you need to be in. Looking at the other comments I suspect the difficulty has come down in the update because I made it to almost 450k on my first go, my only criticism would be that it occasionally felt too generous as I think there were times where I pressed the button too late for the sprite to switch lanes in time but still didn't seem to get punished for it.

You would be correct! The difficulty hasn't come down exactly, but it was adjusted (lower max speed, speed gain is on a curve now, traffic density was increased) and I finished the combo counter which resulted in higher scores. There's also a lingering collision bug where the colliders "miss" each other at high speeds, but I haven't reworked that yet to use interpolation properly - I believe that is what contributes to the "too generous" feeling. I'm going to do a few more updates after the jam. Thanks for playing!
