This is the classic "board" game
Battleship.
When rotating ships during the placement phase, the CTRL key is used, that should be the only element that needs changing (for MacOS) to get the program working in other GUI OS's. *I think*
The ship images were created by Gemini (Google's AI), but needed considerable editing since the AI insisted on placing the aircraft-carrier's super-structure in the middle of the flight deck. The AI also couldn't cope with making the ships particular (relative) sizes. Despite all this, I think the AI did a reasonable job.
Enjoy,
