NULLBYTE

CasualSimulation

A puzzle about reading someone else's code and the one-byte mistake. A whole little machine on one screen: 256 cells, four registers, a stack. From "which way the stack grows" to a chain of borrowed code. You win not with the right answer, but with what the machine actually did.
