The lockdowns hit a lot of us with depression and multiplied a lot of anxiety, and truthfully, while I like this type of content, Sexual and pornographic content does not mix well with depression. You are not alone in your struggles, and beating yourself up over it doesn't help. I've essentially just started getting my life back together since all of that happened myself.
Personally, I don't feel any need for you to repay me as someone who got the demo, if it helped support you then it was worth something, and even more-so if you move on to new projects. I think you show a lot of potential as a game dev, and I look forward to playtesting your future projects, however long that takes. I am little if not patient.
