personally, i found this lacking - the gameplay got repetitive and boring quick, and easy when you realize when music happens, the rock is dropped on your current position, so you just move from previous position to a new one
the best charm was the visual style of the low poly 3d with a realistic rat texture thrown on, that was cute and my favourite part.
with some polish, various levels aand more of a 'puzzle' feel with different things to scale, different obstacles, this could be super fun! but this just wasnt for me
