First day over. Mostly spend on brainstorming some ideas:
Bubbles / Drifting / Puzzle Game / Snow Globe (Holiday season) / Tentacles / Space Station / Gravity / Zero Gravity / Fuel Tank Control / Space Suit / Alarm! / Endless drifting / Single button control
I checked out some boiler plate graphics from OpenGameArt.org. Probably will need to make some of my own to get what I want.
