Congratulations on the submission and I know absolutely nothing of Scratch, but I imagine that what you submitted likely took a lot of effort, so well done!

Simple mechanics and an enjoyable little game loop, although unfortunately the player character's collision with the environment hindered the experience as it was fairly easy to almost get stuck, and then I had to stop playing when I got soft-locked between a cloud and a platform (in the transition to the third environment).

Nice work overall though!

I got up past the ice biome and them the character got stuck ):

Very impressive that you made this in scratch! Nice work! 5 stars!
