"When it comes to additional help, I don't think that I'm a good enough artist to contribute, sadly. Even if I was, I'm sure I'd be rusty. However, I've been wanting to try making fanart for fun. If any of it turns out to be surprisingly good to the point where you'd like to use it, then you'd be more than welcome to! Just out of curiosity, which assets are still needed and for lack of a better term, which characteristics would make them technically and/or thematically addible?"
I would love to see fanart! In terms of fanart that would thematically work in the game, I was planning on re-doing the dream images of Marion and Ashanna, since currently it's just distorted versions of their sprites. But if you do decide to make some fanart I can find some way to incorporate it into the game, regardless of what you makes. :)
"Edit: For some reason, I'm still struggling to decipher 15 10. I've tried using both the door and the ghost as starting points for different combinations."
Ah, sorry, it sounds like it's bugged. I'll do some testing and determine why it isn't working, thanks for your patience.
"Secondly, I found some more money in a tree by the river! Who keeps hiding money and why?"
Haha, there's no reason narrative reason, as of now. I thought it'd be fun to hide a few things for the player to find. :)
"Thirdly, how long should it take for sick animals to recover? Do they need to receive all of their missed feedings or do they require less than that?"
The animal feeding system probably needs to be re-worked a bit. Animals start out with a "mood" rating of 5. Each time they're fed, their mood improves by 1. Missing a feeding decreases their mood by 5. As long as their mood is >= 5, they'll stay healthy. What I likely need to do is add a cap on mood rating and cause the animal to die if they aren't fed for a couple days in a row.
"Fourthly, Orwin tried to give me a burger from a messed up order, but he accidentally gave me pumpkin seeds.
Fifthly, after you dig in the lower right corner of your farm, you can still receive hints about that.
Sixthly, long after the story has ended, Millie will still occasionally invite you to take refuge in her home if needed. Parker will also talk about how the library might have a secret."
Duly noted! Thanks again, I've compiled quite a list of things to fix with your help. :P
