Run the game:
go run ./appBelow is an incomplete description of language features and conventions we can consider implementing.
A virtual machine will execute the program running on each tower. A certain number of instructions will be executed, based on the configuration of the tower's "computer" and possibly other game-world factors. Then, the state of the virtual machine after the instructions have been executed will be converted by the game engine to tower updates.
For example, there might be a global variable or register within the VM that determines whether the tower should rotate left, right, or not at all. The state of this variable after execution will be read externally and used to decide how to update the tower in-game.
