Demo is available on the website page: Primemoversgames.com
The shared link has different versions for different PC platforms, including Windows (both 32 and 64 bits), Mac (both 32 and 64 bits), and Linux (both 32 and 64 bits).
The demo is a brief part of the game (About 30 minutes) that should show how the full game will work, but should be just as enjoyable.
Enjoy the demo and good luck solving the puzzles and making the decisions!
