Well I had a rough idea of this game at the end of the weekend but, what with work and cricket, I have only just really got anything done worth showing now. You can see me few lines of code and crappy sprites at bitbucket
The idea is to build logic circuits from basic units e.g. AND, OR, NOT etc. and gradually building up to more complex things. I have an idea to start with a half-adder then an adder and build up to 8 bits(theme!); then onto multipliers. We'll see how that goes.
Time for bed now, good luck everyone.
