after grabbing low hanging fruits now it's time to adjust workflow. and have a better harness.
because what is happening right now that you start very enthusiastic because it's easy but now the scale problem comes. to tackle it I need to rethink approach, guard rails and tests.
should i go one module by one module? that will not work as you want to test code against original game. maybe i can have a module but then i will not get everything to 100% match because of optimization but maybe its viable strategy to get as much code as i can.
or should i start by extending main, and going deeper each time? this approach is more fragile but allows to have something buildable all the time.
or some 3rd option? hybrid approach? should i have tests ready? should i start with tests? can i run specific functions from the game to write down tests?
so the way is clear but now workflow should be tigheten up
