I always appreciate constructive criticism, especially when it's clear that the player was actively engaged. I'm happy to see your response! My games are quite niche in terms of how they are played, and the stories they tell, so they can't (and weren't meant to) reach absolutely everyone, but I do try to get a few more players on board when I see an opportunity. Difficulty is something that I can offer more options for on my end to allow more players to have fun, so it's certainly a very reasonable concern!
Try some of my other games if you have the time, perhaps one of them can offer a more fulfilling experience!
