Shade

This is a very short and enclosed game, without a clear goal at first. After a bit of milling around, you'll realize how to progress through the game as you start receiving tasks to do; this worked very well, even with the later complications that crop up.

After a while, the tasks get stranger and more specific, and as this happened, I ended up progressing by trial and error. For such a compact and otherwise well-realized game, it's strange that it doesn't respond to the specific items/tasks on your list, and so it veers a bit much into "guess the verb around the general vicinity of items referred to in the tasks" territory for me. (For example, when I was asked to (Spoiler - click to show)"unclog the shower drain", the way I eventually managed to trigger that step was with "take shower", and I also had major problems with removing the package from the kitchen storage.)

Despite that, the game works almost all of the time. The story is interesting and vague, and although I felt it became a bit too silly by the end, it's a very good example of a creeping feeling of dread that really only IF can give you.
