Looks great! The main mechanic is a neat spin on a Sokobon kind of block puzzle and each of the first few challenges are designed in a way to get you to understand the way jumping and dropping blocks works. Well-executed design, great look.

Two issues I ran into. In the first puzzle with the four movable blocks, I managed to softlock the game by trapping myself with a block on the ground on one side and another above me, creating a thin gap. Enough for me to fall to the ground but I can't jump back up. A quick reset would be a helpful "polish" task. The other issue was I had to fall on a spike and reset to get the blocks to appear for each challenge (if the block was supposed to spawn on a spike). Falling in the water didn't get the blocks to appear.

Minor bugs, but really nifty design and a solid foundation for a fun puzzle platformer. Love the look!
