A really great idea for a platformer game that has a lot going for it! Creative movement system, clever level design and amazing art!
I had a fun time playing through the 4 levels on playday (incredible how you managed to furnish all of them to look so beautiful in such a short time)!
Often, I didn't really feel "urged-on" enough in the game...with the idea of rolling up into a ball and zipping around, I would think that it's a game all about speed, but there were plenty of segments where I was able to just walk over the long segments that were made to roll over without any punishment (besides not getting the "rolling coins", which didn't exactly serve as a big enough motivation for me).
Some camera movement was a bit off in places, where having to re-adjust the camera myself felt a bit wonky and stomping on boost panels to get a higher jump didn't feel as impactful as I would have expected it to feel...two more minor issues.
Overall, it was great fun speedrunning this against my friends and just awesome to see what you came up with!
