Coding
This is not a no-coding asset. And while cards and abilities can be edited directly from the data files (scriptable objects), you will need to edit the code to add features or change the core game rules. I made the decision to not include any custom editor GUI to keep the code as simple as possible and useable for a varied level of programming skills. I put a high priority on keeping the code clean and well structured. We have a Discord community for people to help each other if you are just starting with coding. And I will be glad to listen to any feedback to improve the code in future versions if needed. More info in the doc.
