I totally loved the idea behind your game (I used a similar concept myself) and liked the other mechanics such as moving platforms. However, it felt a bit confusing: in the first level you introduce a button mechanic, yet the rest of the levels use sliders to rotate the platforms; and in certain moments it wasn't clear where the snail could move, Also the camera movement was a bit odd in certain moments, perhaps I did something I wasn't meant to while trying to move the snail.
I can appreciate the effort put in level design, mechanics programming and art for this game and I have to say you did a good job, keep it up!
