The compass is right. You just probably miss one place with puzzle for the key. Clue for the key location was in the computer notes. Feel free to message me on twitter if you still can’t progress.
Thanks for your feedback. If mouse invert is requested I can include it. I just don’t know anyone playing with mouse to actually use it as it is mostly used for flight simulators or consoles/gamepad players. I can include it in next update.
