It's pretty good! But the mobs are missing, the time of the jump boost effect is maybe a little short... Also for some reason I wasn't able to break the blocks in 1-2 that were blocking the path, maybe it's just a glitch on my side. And a hidden block is missing in the world map, next to a cloud. Looking forward to see what's added next.

Ok? Thank you
