This just started on Kickstarter: http://www.kickstarter.com/projects/1365713495/chainsaw-ninja-in-space "A stealth-based 2.5D platformer with multiple paths to victory including assassination, sabotage, and outright glorious destruction..." The video doesn't show off the game much yet, mostly the talents of those involved. But the text is very informative as to how the game/gameplay will work. The main dev is a long time volunteer game reviewer/journalist in the Mac game space as well. Hoping people support his efforts. The game looks like a lot of fun and I know he will be doing a prototype soon. So lookout for updates.
