Howdy,
So theres a new game from Zachtronics, TIS-100, that is pretty amazing. Very similar to SpaceChem (same developer).
Its a small computer system with a number of simple CPUs where you solve puzzles by programming the nodes with a small number of asm instructions, a register, a backup reg and four I/O.
Since half the fun is trying to optimize your solution to get lowest cycle count, people should post their steam names if they want to challenge each other (mine is theflamingskunk, feel free to add me).
