I hate to be that guy, but are we ok with AI-generated voices? Maybe I'm just salty because I think using stuff like Copilot should have been allowed, but it seems likely that this voice was trained on actual samples from MGS.
Aside from that, this is really well made all around. I agree that indicating which camera is selected would help, but wouldn't go so far as showing the player location on the map as part of the fun for me was figuring out what I was even looking at.
