Also note that one of the underground snow caverns has a dead end where you can't go back up.

Is there a particular reason why horizontal movement is slower in the air? It makes platforming unnatural. I would be willing to fix that and possibly refactor the movement code...

Definitely, I am not commenting on the overall movement speed, but horizontal movement in air should be equal to that on land.

I just cloned the game and I think it's amazing! However I do not think there is an immediate advantage to porting to 3.0, and instead we should better wait...

This is so cool! Thank you!
