Neatorama reader Dougall Meloney wrote about a neat collection of "find your way out of the room" Flash-based games at Gotmail.jp:
Here are some beautiful flash based on line 'puzzle' games, similar in structure to 'Mist' although nowhere near as massive. The graphics are great, the game play quick, non-violent and fun.
Hint: click on EVERYTHING - you are looking for stuff to solve the game under stuff, behind things etc. These games rely on your memory of what you have discovered before.
Link - Thanks Dougall!
