Generally you should have an idea for a game before you try and code one ;)
True, that's why I haven't started writing the game yet. :) This is just some test/feasibility code I did to see if I could do a 3D snake. I was originally just going to do a 3D version of that other snake game I started, but I decided I want to do something a little more original. However, how about you ramp up the difficulty level and write a Mercury clone?
Yikes! I've never played the game but looking at the screenies I'm guessing there's some pretty hefty physics involved. Anyway, I prefer the dynamic of controlling a snake-like thing, rather than just a blob of mercury. :)
