Hello, my submission to Never 51 is Tightrope -- A solo card game.
To play it, you need two decks of cards with backs of different colours. The instructions and game board are free to print in the game's zipfile. The game board is entirely optional.
Your goal is to collect resources (e.g. card) to play missions and defeat the Opponent, a malevolent foreign power who has invaded your country.
The game is pretty basic but fully playable, I am planning to keep working on this project to add a deck of special cards to add specific missions and bonus powers. Enjoy(?)
