As a team, we've discussed a few ideas. One note, especially due to the short time and inexperience, we've decided to do a 2D game, likely in pygame.

Possible theme ideas: 
Al Gore is really a mad scientist who has financially invested in heaters. By promoting environmental awareness, he is really trying to cause a global cooling effect, so demand for his heaters will skyrocket. It's up to us to stop him any way we can, or be a minion in his army of anti-warmth.


 Possible game ideas: 

• You run a factory, and have to shoot holes in the ozone layer faster than Gore and company can repair them. Similar games would be Space Invaders or Red.  
• You delve into his eco-dome of horror, fighting off his servants, until you can destroy Gore himself. Similar games: Dungeons of Dredmor, Nethack, possibly The Binding of Isaac
• You are Al Gore himself, setting up turrets to destroy greenhouse emissions, with your score determined by how much you can sell. 
• You are an alchemist who is working on several recipes, and only by combining things in just the right way can you succeed. (Mastermind, or possibly a bejeweled kind of thing) 
• You are a tiny scientist, who has dreams of growing immense. One day, you discover a formula that lets you absorb other forms. Kind of like a 2D Katamari
