I like the idea, but what this game really needs is solid platforming polish.
The movement is not snappy, the jump is way too floaty and the hitboxes are super harsh, with invisible edges. It's also always a bad feeling when the platforms you're standing on don't take you with them as they move (the horizontal ones). Sadly i could not get past the first level because the trampoline note was buggy as heck for me. Also, there's something off with the resolution scaling, i had the settings button in the middle of the screen.
I get that you had to implement scaling somehow but having a 'stop' and 'go' would have had the exact same effect on gameplay.
To mention some positives, the art was refreshing, the music was lovely.
Well done!
