Very enjoyable! Good job!I made it to level 8, made 3 pyramids, but when I reversed it counted as a failure when it touched the sand :(
Thanks for playing! A failure is triggered when the game determines you have no valid square to go to, and the character can't jump gaps or overcome obstacles more than a single pixel high, so my guess is you ran into one of those scenarios. Or maybe you stumbled onto a bug that I did not encounter!
