Looking at this, I realize I'm not a fan of these kinds of games. That being said, I can't help but appreciate this. The game is really designed well. The graphics are quite nice as well. It has most of what you would want in a game like this. You are more anxious with the timer.
I'm not sure if that's a good or bad thing. It's just executed well. I was surprised I couldn't pick up the rubber bands or paper clips. I'm thinking too much like MacGuyver. I have a hunch those colors mean something.
