I had to come here at least to leave a review of the demo. After playing the Steam version for 18 hours, I can only say... I love it!
It's funny, I really didn't like Stardew at all... I played for about 20 minutes and requested a refund so hard that Steam gave me my money back right away. But this one! Oh my god... I guess what I needed was a more interesting farm... A Lovecraftian farm.
I only encountered one bug: sometimes, after the moon cutscene, the frame rate drops to 4-7 fps and stays there. In some kind of weird limbo between freezing and updating the crops. But other than that, it's amazing.
Here's my 18hr build, kinda balanced between magic and physical, prob the worst build but is my build. There are many like it, but this one is mine:

Thanks for this amazing game you're making, see you on full release!
