Yeah, my primary audience for the game has always been those without ADHD to help them understand what it's like. Most of the ADHD effected people that playtested the game had a similar experience, myself included. I found it emotionally draining, but there were some with ADHD that didn't have that reaction. I think it depends on how ADHD presents in the person.
If you have anyone in your life who has difficulty understanding what you go through, pass this along to them. I hope it helps if you do. 🙂
