The music and visuals were good, and so of course was the gameplay.I found myself surprisingly motivated to keep trying to see how far I could get (made it through 30 shapes before failing.)
One minor complaint, though: there were quite a few times where I clicked a shape right as another shape with fewer vertices appeared, and the previous one didn't count anymore.I wonder if it would be better to allow for a momentary buffer wherein the previous shape is still valid for cases like these. Granted, that may just be me wishing for an easier time.
Either way, good stuff
