Thank you for playing, and thank you even more for providing video! I hate to say that I laughed at the end, but I did.
For healing, there are several ways. Obviously consumables like potions and food heal, but like you assumed, you also heal inside a house you've purchased. You can also drop a bedroll and sleep on that for health. At the moment I don't want to do a hunger system because I feel like it can come off as a chore. But unique buffs for being satiated is something I want to try.
You're definitely right that they feel very similar right now. I'd like to integrate some behaviors for them so they might try to run and kite, or support their allies. As I add more spells, hopefully that'll help too.
I'm glad you figured out the ruby statues, I think you might be the only one haha. Thanks again for your comments and I look forward to hearing your feedback in the future!
