some of the jumps are a little to tight for a puzzle game. The movement fells alot better.
i feel the exits are not that obvius. I restarted the tutorial level multipule times until i figured out how i was suposed to leave the level.
I found some places that it was posible to get softlocked, i know there is a restart button but it feels kinda bad when you just figured it out just to have to do it all over again.
The hubworld is a good idea. it is kinda bad how you spawn in on the left and all the levels are more and more to the right.
A few minor things but all in all a really good demo.
