The votes are in and 8 (four member) teams have been formed. The team I have the pleasure of working on will be taking this pitch (here) and turn it into a prototype.
When our team met on Tuesday, we started to look for similar games to get ideas from. We found these games:
Marble-mania
rube-goldberg machines
Marble madness
Perplexus
Money Maze
Bllz Obstacle
Super Monkey Ball
Rock of Ages
Peggle
Crayon Physics
Decolord
CivBalls
Gravity Master
Katamari Damaci
Start here
Cube maze
Amazing Marble Maze 3D
Ballstix
Ion Charge
Echo Chrome
Mr Gravity
Grav-bot
Proun
Tetrisphere
This idea also reminded me of Screwball Scramble that I used to play as a kid:
Now the team will have to come up with a prototype that finds the fun in our game idea.
