My three favorite games are Tiny D6, Tunnel Goons, and 2400/24XX.

I decided to mash up Tunnel Goons x 24XX to see what came out. This is about the third iteration of that effort. I think it's pretty good, a respectable descendant of its antecedents.

A key thing about this engine is that the character always succeeds, but sometimes they do so at significant loss. "Life itself" can be at risk, of course. So can many other precious things.
