I think I need to learn Godot or something for the prototyping phase. Even if I end up writing the whole game twice, iterating on gameplay ideas in 6502 assembly does not seem at all like a more efficient use of time. I was so excited to get something running in VICE but now I'm overwhelmed enough by the high level concepts (proc gen maps and the dual grid stuff at the moment) that trying to think it through at a super low level just isn't working.
