I love a good puzzle game and this one...rocks! I read the instructions but I still didn't really understand how to play the game properly until several failures. The overall thematic of this game is fantastic! The presentation and gameplay captures the Sisyphos greek myth. I love that "ROCK DROPPED" screen. His look of anguish definitely matched my after my double digit attempts.
I'm not sure if it was intentional, but once I realized you could move backward, it made the game much less challenging. I was beginning to think some sections were impossible until I realized I could step back without losing balance. I don't think this is mentioned in the instructions, and I would definitely recommend including it.
