Sokoban with a countdown! The puzzles worked well, and properly teased my brain. I had to grab a hint on the final level too, so I appreciate the hints not just directly being the solution. I think the idea of pushing rocks without also moving forward was what threw me off with that final puzzle, since it's the only time that mechanic's used, and a complete lack of an undo button felt a little bit hostile, too. I don't think this needs much work though. While the music can be a little repetitive when solving puzzles, it and the artstyle are very well put together. I think this just deserves more levels, to be honest.
