This is such a cute lil' puzzle game, what a fun take on sliding puzzles!
The art-style and music are really pretty, they feel professional-standard, and added a lot to the game world. The controls were simple and the tile-sliding was responsive and didn't cause any issues - it was satisfying to move them around.
I did get stuck on the final level, I didn't realise I could move one of the tiles for ages (you can probably guess which one), but after restarting it a couple times it clicked and then I was home free.
Great game, good work to the both of you!
