My Diamond Baby is another single-room point-and-click game, this one was created by Project C-Time! and Haruo Seto.
You start off as someone on a motorcycle on his way to give an engagement ring to his girlfriend. On his way he is involved in a motorcycle accident. When he regains consciousness he finds himself locked in a room without the engagement ring.
This game is unique in that there are multiple challenging puzzles within the game, that you have to solve in order to progress further. At least one of the puzzles changes each time you play.
This is by far the most challenging point-and-click game I have ever played. Imagine Crimson Room, Viridian Room, and the Blue Chamber all rolled up into one. One thing that makes this game more difficult than others is the very tiny areas you need to find and click on in order to progress. Some areas only giving you a few pixels.
My Diamond Baby is definitely for the point-and-click gaming pro's. It will test your wit and intelligence, and ability to think "outside the box". It's definitely not for those who get frustrated with the easier point-and-click games such as Escape the Room.
This game was just recently translated into English, making it a little easier to play... but not much. When I first played it, it was still in Japanese.
The ending to this game is, in my opinion, one of the better endings to many point-and-click games. I know it's hard to create a good ending to these type of games, but I think My Diamond Baby does a good job, especially if you watch all the way through the credits until the end.
