Well executed idea, I like how the challenge gradually builds up as more cars come in.
Thanks also for your timelapse video - I've messed with the PICO-8 for a while and Picotron looks very interesting!
It's awesome to see another PICO-8 submission!
For the cover image, I just laid it out manually in GIMP, using the basic title and one of the sprites from the game and putting them on a background matching the PICO-8's color palette. I felt it didn't count as part of the 3 hour limit since it's part of setting up the game page.
This is a fun gallery shooter! I appreciate the targets being actual physics bodies instead of just objects with health so you need to keep up your fire and aim carefully. I appreciate the effort you put into the cover image too!
I couldn't defeat Cathy Mitchell :( An audio cue for when she's attacking might help since it can be hard to notice before it's too late otherwise
