Delightful game and I loved how even very "simple" puzzles hid a lot of complexity.
In a lot of Sokobans the player feels very "weak" like they have very few tools to manipulate the game state. Here the player is very powerful and yet the puzzles still require a lot of thought.
I also appreciate that this power means there are a lot of valid states along the route to a solution, that solutions come from figuring out specific phase changes rather than carefully threading a needle of perfect steps.
