Hey all, I have been recently reminded of this guy, and I think ubuu would enjoy his games quite a lot.
Basically, he makes flash games, most of them focused on exploration and puzzle-solving. The illustrations are very interesting, so are the characters. Also, delicious ambience and great general atmosphere. Interested? Great, read on.
The first game I'd recommend is the submachine series. It starts out as a very simple escape-the-room kind of game, but the story and gameplay develop, most notably in parts 2-4. It's a fairly eerie experience. Interdimensional portals, artificial intelligence and cats are involved.
If you never played submachine before, I suggest trying out the sub network exploration project first - http://www.submachineworld.com/subnet.html
You jump around the network, from room to room and look for clues. You don't have to do it in order. Each area is different and only loosely related to others, and some of the rooms contain fan-submitted theories. There IS a last room however. But more are being added periodically.
The second game (pictured) is daymare town. This one requires exploration and finding items/solving puzzles as well. Excellent soundtrack. Quirky characters/creatures. I found this one to be rather depressing, though.
