Played on Windows 10 in the itch app using mouse and keyboard and a NVIDIA GeForce GTX 1660 Ti.
Got repeated errors pop up in the Development Console the first time I tried to move: "ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: index"
In the Player.log file in my LocalLow\Studio Hunty\Compasscope folder:
<RI> Initializing input.
New input system (experimental) initialized
<RI> Initialized touch support.

All of the onscreen non-mouse button prompts were for the "W" key, but I was able to figure out the controls, connect the three landmarks and open the door. Using the telescope as a lever is a clever bit of gating, but the central triangulation puzzle basically solves itself at this point.
