Man what a crazy theme. To get over the hump of idea generation and start coding I had to mash together a few genres.

So right now I'm shooting for

Survival + Match 3 + Step/Gridbased(Rogue-like) Movement + Tower Defense

It's a weird idea, but I think I can do all of those things. Plus it gives me the added bonus of really only needing 1 level.

As I wrap up the night I have this with grid movement in GM2. Which I have never used before but am seriously liking how quick I was able to plop stuff down!
