Wow, what an amazing game and writing. I stumbled upon this all a bit randomly after watching a youtube video about your game. I might be reading into some of this a bit, but I wanted to share some thoughts I had about this game in relation to the process of therapy and how I saw some emerging themes with the writing/characters while trying not to spoil anything.
The experience of discovery, communication and growth in a parallel context to the child, caseworker and the grandpa/entity was fascinating. I almost felt as though this entity was providing more of a therapeutic experience for the child than the caseworker was, and a lot of what the entity was discussing were aspects of roles that a therapist plays. Reflecting the inner wants and desires of the client (the wish) while also encouraging them towards exploration and change (the contract). There are also themes of the inability/lack of effectiveness/lack of training with therapists to really enact fulfilling therapeutic change within their clients as opposed to the want/need to just permanently fix the perpetuating stressors (parents fighting) which would in some ways aid the development of some clients/children a lot more than therapy could offer.
Regardless, really great stuff, I will be keeping an eye out for your future games. Keep up the good work.
