My high score was 1437 :)
I really like the visual/audio FX. Gave me big Canvas Curse vibes! The tech also feels impressive; any game where you can physically draw in collision boxes looks like magic to me.
Gameplay-wise,90% of my distance traveled occurred when I got a right-arrow spawn. It feels a little bad knowing that my efforts during non-right-arrow segments amounts to very little score... and getting a left-arrow spawn just kinda felt bad outright.
It also felt like the character hugged the right-side of the screen a little too closely? Like, it felt really good to go fast, but simultaneously it felt really bad to hit a galaxy I couldn't see and only had half a second to react to. It encouraged moving much slower than I found to be fun.
Overall, though, I think this is a nice entry :) I can understand why you're advertising it on a lot of other peoples' submissions haha
