entertaining
this game was pretty fun. i had a good time playing it but a couple of the levels which were intended to be rather difficult, could be easily completed by simply waiting for the sand to fill up to the height of the exit. the one i'm thinking of in particular is the one where the walls are segmented, the intention being that you would have to wall jump from side to reach the top. but like i said, all you have to do is wait. perhaps some more obstacles could solve this problem. overall, though, it was a good game.
