Game type: browser-based point-and-click adventure (short)
Time demand: Brief game
What it is:
This was a fun little game that I stumbled across... It's shorter than I'd like, but it's a point-and-click adventure where the goal is to make your way out of a few different rooms and escape from the house. You click on various things, collect items, use them with each other and on the environment, and eventually make it from one room into the next.
The twist, so to speak, is that there are multiple ways to make your way out of different rooms, and different little unnecessary things that you can do on the side, and almost all of these things either raise or lower an alignment bar that you can see on the bottom of the screen. So as you play in one room, then move on to the next room, the scenery will be different depending on your alignment when you enter. In some rooms, there may even be different ways to escape the room/end the scenario depending on your alignment when you enter. And your final alignment determines which of the various endings you get.
It's also a nice little brain-twisting thing, so short as it is, I'd recommend it for a nice little time-killer. Fun!
