Hi! Thanks for taking the time to write that extensive feedback, it really helps! About the seeds not sprouting, did you go to the next day by clicking the bed icon? I tried to explain in the description since we didn't have the time to make a tutorial, but in-game help other than the question mark tool that you can click on a plant with to see what's wrong would indeed be useful.
It could also be that you overwatered the seeds I think? I you haven't completed a quest yet I'd love for you to give it another try, there might be a cat in there somewhere :D
Thank you so much for taking the time to play our game and review it so thouroughly!
