Keep It Alive!
I really had my problems getting something out of that theme (after all, it applies to basically every game with a "death" lose condition plus a lot more things), but in the end it was fun, a great learning experience and I'm fine with how my game turned out. Thanks again for the feedback everyone, I'll remember it next LD. :)
But that's not why I'm writing this: The overall #1 games of both the compo and the jam are named "keep it alive" and I (for some reason) find it ridiculously cute. Like the theme named it's first-born children after itself. The results for LD46 will certainly look fun on Wikipedia. :D
