Felt really nice playing it, and great job with the camera dynamics, like more points the better photography! I never got over a C, but I played through several times and had a ton of fun.
Points to consider: mouse sensitivity was a little high for me, but not excessively so; maybe a settings bar? Then also like @randomphantom said, motion for buns, and then it would be nice if the crouching was toggled and then it would be easier to photograph while crouching.
Great submission BlazingMammoth! Really well done
