Summary: Machinarium is fun to play, but I got maybe halfway through when all my saved games all disappeared. Where'd they go? Turns out that your saved games disappear should you clear your browser cache. Clearing your browser cache is recommended maintenance, and essential for developers such as myself.
Summary: On a PC, the games works wonderfully well with Flash Player 10. I heartily endorse all the positive comments posted elsewhere about the game itself. However, Mac users need to know the game does not load with Flash Player 10 in OS.X. The workaround is to uninstall v.10 and re-install v.9.
Summary: beware mac users, although the limited fan edition says it's pc/mac compatible, it does include, at least in my case, only the windows version, so, if you want it for the extras, fine i guess, but if oyu intend to play you won't be able to use it in mac os. too bad.
