The cost of code is truly low. Lately, I've had so many game ideas and so little time. Initially, I considered hiring a Vibe coder, but relying too heavily on manpower is outdated thinking. So, I forced myself to find ways to scale with pure code. Today, I created an agent to help me review and test games, replacing what would have taken me two days to do myself. Of course, a bot is a bot because it lacks basic game knowledge and general understanding. Therefore, everything from game rules and objectives to experience standards had to be translated into code. This step sounds tedious, but Codex can write the logic in two minutes. Going a step further, I required Codex to understand the purpose and effect of each item (because it's a roguelike game with many items) from a literal perspective, and then translate this user experience into code that the bot must understand and verify. As the amount of code increased, the bot essentially became an agent and a workflow, but all of this was very low-cost, as long as you have the patience. Turning all subjective experiences into verifiable code logic is also a requirement for designers in this new era.
