Heh, I really like this, I see you took inspiration on Sonic RPG "Action" mechanic, I really like the simplicity to this, I can see it as a mobile game that goes on and on, congrats to all!
I honestly would really like a downloadable version tho...
PS: I finished everything at first try! (doesn't mean I didn't grind before entering some areas); but some medals didn't activated
Edit [March 4th, 2021]: I just got in again today and got all medals all of the sudden, yey?
