OK im more a fan of action games but the hidden puzzle type has always appealed to me.
When i saw that this was 'free' i thought id download it and give it a whirl. This is 'free' but only for the first 20 minutes which is enough to give you a good taster if you use the casual mode.
The graphics are good and the speach is a nice touch too, ive certainly seen a lot worse.
No real niggles but i would recommend starting it in full screen or you cant get access to the all important menus.
This could be the first puzzle game that im going to have to buy.
