Nice little puzzle platformer. At first I thought the controls were a little tedious with all the rearranging needed to get through the levels. However, it appears that was only in the tutorial to help the player understand the ways the blocks can be used and the design of future levels appeared mindful of this. Well done. The graphics are nice and the music pairs well, too. There's a ton of content here, too. I think you could have gotten away with just world one for the jam as those are plenty difficult. The difficulty in world two got really high and I spent too much time trying to figure them out. I guess that's a good thing!
Well done on making this in 48 hours!
