This was a pretty good game. Using the scroll wheel to control player size was a good choice. However, some segments felt too tight. Additionally, the ability to jump higher by shrinking didn't feel obvious. Overall, I'd love to see this idea expanded on. Nice work.

Thank you for the feedback! Fun fact: The ability to jump higher by shrinking was originally just a bug/exploit, as everything scales with the player when you change size, bigger size = more gravity and jump height, smaller size = less gravity and jump height, so I found this accidentally but I really liked the mechanic, so I tried implementing it into the levels and almost have it as if the player didn't know they were doing it, though it's probably kinda obvious that they are doing the little bug thing.
