This is my game pitch: “A game where you control insects that have to collaborate to gather resources that power a Shmup mothership boss – the insects morph into the mothership”.
You basically control the NPC side of the Shmup, in a two stage game: gather resources and then Shmup action! Also the resources gathered are used by the boss (you) in battle. So if you gather just a few of them, you may end up dyeing to to the enemy.
You can play a very rough build here (nothing yet aside to allow moving with WASD + Jump with space): http://dl.dropbox.com/u/11453596/LD/23/sb/sb.html
