WOW, it's definitely Switch material! I want to play it with my husband :D. It's just that our controller setup isn't really good at the moment. A co-op game is WONDERFUL. There aren't that many of them that really have this level of non-violent cooperation, so I look forward to the balance tweak!
Wow, 20 years! I didn't even realize GM was that old! Your ability to create all that in 3 work days is astounding! I hope that I can get that good someday! I do some low-level programming for a living, but I'm new to gamemaking, so the graphics and sounds are my weakest area. Our game definitely wouldn't have been as good if it weren't BOTH my husband and me, so you doing it solo is definitely amazing!
Yeah, I can't really think of how to deal with the corners other than to make them curved looking and when you have an access to the analog stick, use that. Or speed through the corners; like it just shoots it around the corner, so nothing is ever in a corner during the "still" time (like have a accelerated tile). It could also just be left there as a strategy element, once the rest of it becomes a little more balanced.
