If you're going to make this your DooM thing, clearly the next thing to do is grab a DooM engine and get to work. (PsyDoom has Lua support even).

But congrats. This is worth being included in a uni course.

It'd be really interesting to push this to that level -- the big challenge likely being that DooM's state (including video memory) is certainly much larger and expensive to swap than an NES save state.

One would have to get really clever...

… and introduce something like virtual memory?
