good game

This is a fun, challenging, and extremely well designed game. The only drawback is that if you attempt to minimize (command + M) it will completely freeze your computer, with the only way to unfreeze it being a force power down. It sometimes does this with the quit function also, command+Q. Apparently some of their other games also have this flaw. Please fix this and it will definitely be a 5 star rating!

Can’t access puzzles if you’re not super speedy

This game requires you to solve the puzzles very quickly and with a minimum of moves, otherwise it won’t unlock most of the puzzles. I have to take my time working through challenging puzzles.. . But I paid for the whole game, and it’s irritating that I can’t access most of the puzzles I paid for. They should at least warn you about this in the description befiore purchase.

Just plain fun!

I wanted a game that would provide a solid challenge but one that would not be overwhelmingly difficult. I like games that you can play and beat a level and advance, only to go back days later and replay a prior level in the persuit of the perfect score. This game does just that which adds plenty of replayability. The gameplay mechanics feel nice with the Magic Trackpad. The ability to configure the graphics levels is a nice feature available in the options menu, as I cranked up all of the levels. Even with the settings set for best presentation, the game played smooth and clean. If you are not sure about this game go ahead and try the free version first, but I really enjoy this entry and believe other fans of puzzlers will too.
