The mouse straight up did not work in the Remake version; the sensibility was super high in the Classic (though I think that's solvable).

Classic worked somewhat (tried it briefly, the training mission). For the Remake, nothing I did worked; I could move with my keyboard and it recognized the keybinds but the mouse was useless, the pointer appeared on top of the game and wouldn't work the camera; also, couldn't select any options when I was in the menus, I had to go using the up and down arrows and enter to select anything.
