I'm using OS 10.7.4 and I couldn't get game controls to work for this game. Neither keyboard or mouse controls worked.

It's also very hard to know how to start the game. I tried clicking on various parts of the Intro Screen and only managed to quite the game. Regardless of trying to fix the game controls, the lack of an intuitive place to even start the game was an odd experience.

This is a pretty Match-3 game. However, at the very end, there is a screen that I've found impossible to get through - the timing is such that you have to memorize a set of moves learned through dozens of trials. Not my cup of tea. I thought that sort of strategy went out with Pac-Man and Super Mario Bros. Oh well. Never finished it.
