Death Inc. has a demo. This is one of those Kickstarter games that I'm watching with interest. Coming from Ambient Studios, which is made up of former devs from games Little Big Planet, Fable, Burnout and Need for Speed, this whimsical game has you playing the part of Death, and spreading the plague around the town.
They are currently as of this writing at 20% of their funding, with 15 days to go. You can check out their playable demo here and see if it's something you'd like to support. Please do if it tickles your fancy, as innovative creative games like these deserve to be funded.
