I really like the idea, but the game itself was quite challenging. I had many approaches and at the beginning I couldn't score more than 50 points (which I know is not much), I felt like the boulders and monsters where coming too fast or maybe am just not very good at it :) Later I scored 119, but only due to the fact that one of the monsters decided to ignore me and passed right trough me :D
Due to the fact that the boulders fell randomly I also had a situation where the monsters were close and nothing could be done about it.
Nonetheless, I had a good time and I really like the cute graphics :)
