My F4D entry is titled Névégis, and will be a Tower Defense-esque game.

Here's an early taste:

The basic concept is you pick up snow off the ground and use it to build things like barriers and snowmen in order to defend yourself from waves of enemies.

Anyway, progress is… progressing. I'm pretty confident I'll have something presentable before the deadline. =)

It would seem that most of you guys are doing platformer-type games, so even if my game isn't as good as some of yours, it'll still at least stand out in that regard.
