Blue Tear
This is a long and detailed casual point-and-click adventure withs lots of hidden-object scenes and puzzles, but it is hampered by technical problems.
First, I and many other people could not get it to run in full-screen mode. Depending on your resolution, it could mean that the game appears naturally as a tiny little window. The way to fix this is to change your desktop resolution: an awkward and annoying workaround. This might make most people pass on this game.
It also crashed on me a few times. This was easily solvable by restarting the game: it continued from exactly the same place.
For those who stay, prepared to have issues with "pixel hunting": you sometimes need to click at the exact right tiny little place for an action to register. This is frustrating, because it might appear to you that you did not solve the puzzle correctly, when if fact you were correct.
If you can stomach those problems, you will be rewarded with beautiful graphics and complex gameplay. The story itself isn't very special, but it takes you through two very different settings, almost feeling like two different games, and features some memorable characters and animations. The voice acting is, as usual for this genre, mediocre.
