A little late on my part but I really appreciate your feedback and wanted you to know I have been considering alternatives. Unfortunately with the way the game is designed, using the fixed cameras and all, I feel if I were to give the player the option to free look it would take away significantly from the style and atmosphere. I very meticulously place the camera shots for a number of reasons. Some purely for aesthetics, and others to guide the player's attention and progression. If I can come up with an alternative control option I'll definitely consider it, but I very much don't want this game to be a third person shooter. I know that seems stubborn, and how frustrating this control style can be, but I hope you understand.
I totally respect that decision. I think fixed camera is a really interesting component. The camera is located in areas that direct your attention towards the focus and it adds a certain cinematic element to the game that works out in a really cool way. I like the fixed camera I was just thinking if there was an option to move towards the mouse instead of A and D, however I don't have any experience making 3D games, so I'm not sure if this interferes with the camera
