Oh my word, I hadn't even considered the impact on accessibiity such as colour blindness! :O 20 is an impressive number regardless, each ship colour has a unique shape (same as the portals) but the sprites are small enough that I didn't think it worth drawing attention to...
Thank you very much for the feedback, can't tell you how much I struggled with /how happy I am in the end with the pathing code, so it's really nice to hear that the effort paid off! And also that the audio isn't ear-splittingly loud - sadly I won't be able to take part in the next Trijam, but week after next I'd like to really work on & understand the audio side of things!
