Thank you! It is true that the documentation of the EON framework does need improvement, and deployment is also a problem when not using full static linking. I must admit that using the Z/X keys to confirm or cancel is counterintuitive for most people, and I originally thought so too. However, it seems to be a default key for many emulators (such as mGBA), so I adopted it. Since the game fully supports game controllers, I hope to provide a reasonable keyboard-to-controller button mapping by default. In any case, thank you very much for your feedback!
