This was great fun. Fantastic idea, had me bobbing my head to the music on every level, and the rainbow VFX on the jump trail really elevated the otherwise simple B&W visuals to make a visual style that was so much more than the sum of its parts -- I was really hoping that that would be where the Memory Lane part came in! I'd agree that the jump window could benefit from being just a touch more forgiving, but on the other hand that made it feel all the more rewarding when those nice streaks stacked up. One additional thing I wouldn't have minded is some way to see the "borders" of where the little void bubbles reach when they're expanded, as there were more than a few occasions where I lost a level because I was standing just a bit too close to the bubbles, but again that could be less a game design thing and more a me-being-terrible-at-platformers thing. All in all though, this was probably one of the entries I've had the most fun playing in this jam so far. Really awesome execution on a great idea!
