A fun little challenge with a funny ending message. :) Basically, you have holes and boulders. Boulders fill up the holes, allowing you to walk over them. However, what makes this tricky is that, when pushed, boulders won't stop until they hit a wall, another boulder, or go into a hole. This requires you to plan several moves ahead or just get stuck.

I wouldn't really recommend this if you're not into puzzle games because, as I said before, it is a bit tricky (and potentially frustrating...like if you're doing well, get yourself stuck, and then realize that you haven't saved in a half hour.
