I haven't played a sokoban game in a hot minute! Cute art style and concept. I enjoyed the fun background music and the use of other sound effects through the track. Overall the art direction is very cohesive, even with the itch page itself. Gameplay made you stop and think with clever level design and felt rewarding solving the puzzles.
I liked the graphic you added to the game page explaining the game rules very clearly. Although I didn't see it on my first play so had to figure out the game rules which didn't take long as it became intuitive after a couple trial and errors - could be worth adding this graphic or parts of it into the first level / tutorial?
