A beautiful and cool Steampunk-themed sliding-block puzzle game - REVIEW: I love this on the iPad and the iPhone, and I love it on Mac OS X. It is easy to get the hang of, challenging to solve, and always fun to show others, with entertaining menu transitions and delightful music and sound effects. Many of these 50 sliding-block puzzles must be rotated to see the sides or the back in order to solve them, and solving the easier ones unlocks the harder ones. OPTIONS: Keyboard shortcuts include command-Q (quits the app), command-M (minimizes the app), and command-F (turns fullscreen off and on). There is a simple how-to-play section, and there are 4 ways to optimize the app for your computer: sound, screen, graphics, and language. (1) There are sliders for the effects volume and the music volume. (2) Fullscreen can be turned off or on, and the resolution can be set by choosing between the common screen widths of 800, 1024, or 1280. (3) Shadows, post filters, and frame sync can be turned off or on, and the anti-aliasing speed can be set at either 2x, 4x or off. (4) The language can be set to either Dutch, English, German, French, Spanish, Russian, Portuguese, Polish, or Italian. SURPRISE OPTION: Interestingly, there is a 10th language available called "LOLspeak" which turns all menu language and puzzle descriptions into a peculiarly enjoyable mess of abbreviated and garbled English. This option isn't found in the iOS versions of this app, and that's too bad, because it's pure silliness and harmless fun. WARNING: There are a few quirks with fullscreen mode. When I have fullscreen on, if I want to minimize the app or just switch to another app, I have to first turn fullscreen off with command-F. Plus, the app will crash if, while fullscreen is on, I press command-M (trying in vain to minimize the app) and then press command-F (to turn off fullscreen). Thankfully, I can still quit the app with command-Q. WISH: I wish I could rotate objects with a two-finger tap-and-drag (the Apple system-wide scrolling motion) instead of having to click the trackpad with two fingers and drag while holding down the clicked trackpad. My trackpad is configured in System Preferences not to ever click - using a two-finger tap as a secondary click and a one-finger tap as a primary click. Having to actually click the trackpad at all is loud (I volunteer in a library), and quite physically difficult (I have Carpal Tunnel Syndrome). In the meantime, I'll just have to use two hands, one for the Shift key and the other to rotate the puzzle with a one-finger tap-and-drag; I certainly appreciate the developer giving us that option.

COGS and opengl - It would be nice of you guys to specify that some systems running 10.6.6 will not be able to run this game due to opengl extensions being unsupported. I would really like my money back because your half-off introduction turned into a 100% loss on my part!!!!

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.
