This game is quite old, but I'd be pretty entertained watching a 15-20 minute of you doing it. http://www.kongregate.com/games/scarybug/chronotron EDIT: It's a level game, so you won't beat it in one. Probably another bad one-shot, but a pretty cool game if you've never given it a go.
This indie horror game called 'Guilt' looks interesting. The article I read said it was "short".

I'd say check out Adventure Game Studio's website. AGS is a free engine focused on point and click games and the website has a lot of really good indie made ones.
