Fantastic game! Despite appearing a standard sokoban, the logic is remarkably creative/unique. Coincidentally, this shares a core mechanic with a project of higher scope that I'm currently working on, so I was already familiar with several key moves and the resultant state space. However, I was still blown away by how strong this game is with so few puzzles. Very effective presentation; the first puzzle on its own is nothing special, but in conjunction with the second stage it really hammers home the concept of the game.
