Just came across this today, and I really like this just from the concept and premise alone so far. Won't comment on too much about the combat yet, as it's clearly still too early in development, but I do like the idea of how to heal. I also love the small NPC interactions from the demo already, and the protagonist herself being big buff lady who gets to be both the player character and the dominant one in a sexual role is really underutilized in the world of NSFW games. Even the dialog choices so far show a lot of personality. Take care not to burn out on developing this, but I'm definitely looking forward to seeing it towards its expansion and completion.
Maybe it's too early to ask for some potential stuff in the future, but it'd be neat if there was an option for Ingunn to become even taller/bigger; I'd love to have that power fantasy of towering over most foes and growing in strength overall. Doesn't have to be too dramatic or giantess-level (though not opposed to it either), but even just being a few heads above most of the humanoid enemies you're planning on would be neat.
Good luck on the development!
