So I played through the game and I have to say I enjoyedit quite alot. I tried to complete all the content I could find. Which brings me to my biggest "problem" with the game. I am quite sad there isnt more game (more story, more enemies to fight, more areas , more customization, more remarks about your character and their quirks, etc.). As for more specific things and possible bugs I found:
1. After I used an oblivion draft I then was no longer able to summon treespirits and the skillbook also didnt drop anymore in the previous spot
2. I did not manage to make two partners pregnant at the same time.
3. There are some typos across the game especially when refering to your or another character ( As an example minor things like "your" instead of "my")
4. I kinda expected to have to defend the dungeon in some kind of siege battle against attackers after I had to build the slime-spawn-buildings at the beginning. Maybe that is still planned for postgame though especially with the hinted evolvement of the police and such in game.
TLDR: Completed & Enjoyed the game, wished there was more content and found minor bugs.
