Don't feel too badly about the lack of playtesters. Until one gets a larger following, it is very hard to get them. I still find difficulty getting reliable playtesters for anything I do. Also, there's no shame in starting somewhere and growing. My first game design was twenty years ago now and while it was a work of love, I probably wouldn't share it. Other projects I have worked on for years and still not had ready due to time constraints and the desire to have them meet a certain minimum standard. We each put out our best work and hope it does well. We see our mistakes and use them to grow so the next project is better. No shade at all to you. It's why I do these deep dive critiques. They help others to see how things are happening and where they might decide to make changes. Good luck on your continued growth!
