I was a bit worried when I saw this as I'm playing on a laptop with a trackpad, so I thought I would just play it for a few minutes and get the concept then rate it... i finished the game.
This was really enjoyable, there were some occasional hiccups where trees and especially toadstools would spawn clipped into the edge of the area. It wasn't too hard to deal with but the toatstools really needed some precise aiming to get them. I also think its very funny that the toadstools were much harder to destroy than the huge rocks.
Well done, this fully pulled me in and kept me playing.
