how do you explain something that you have to "feel" to get? it's hard to explain even to humans, the best you could do is tell the ai to dial the ARR, DAS, DCD and SDF to be within reasonable standards (2 frames, 10 frames, 2 frames and 6x, the default values in tetr.io ), but first you would have to actually get the rendering to be a constant 60fps, and have no random delays, ideally, which would require a lot of tweaking. but generally speaking, how do you explain something like the "feel" of the controls without actually trying it? human developers can test the game, and "feel" when the movements are janky, an LLM cannot. even if somehow LLMs got faster, smarter, and could understand this feeling I'm describing and they could perform actions in 100ms, that would still be too much delay for it test the interaction.
