Thanks for giving such detailed feedback, and yes I do love to hear from fans, because it's also a great feeling to know there are still people discovering my series and wanting to discuss it. Seriously - I'm very lucky to have even a small fanbase of passionate players, and that Batty has earned some popularity in the retro gaming scene.
There is something required to truly "finish" the game, but I'll let you try to find it yourself. As for the navigation, that was an aspect I did redesign in the sequel. I'd be interested to know which style you prefer when you get to that one some day.
