Cool puzzle idea! The art is good too! But I have 2 issues with the game. Firstly, it's a bit difficult controlling the squirrel, especially if you rotate the boxes. The controls may get inverted or you'll have to press the right arrow key to move up etc. Maybe this is intentional, but I would have prefered if you could move up and down with the up/down arrow keys instead of left/right. Also if you collide with the snails they will shoot into the air. Maybe this is also intentional, but it looks a little buggy! And finally, the snails are very slow (I know, snails are slow) but it's kind of boring waiting 30 seconds for the snail to make a full loop through the box. My recommendation is that you expand the map (add more boxes) and make the game more fast paced! You've got a good base for a puzzle game but it needs to be improved on a bit further. Still, great job!
