Hello, thanks for the feedback.
I agree that healers can be a bit too aggressive with their healing at the moment, I'll probably lower their target range somewhat in the future. The friendly unit AI in general is something I'm hoping to improve.
As for the idol statues, there are actually already 4 guaranteed to generate on the map, with a chance at 5. The first 3 will always be one of each resource type too. They can appear anywhere on the map though so they can be a bit hard to find sometimes.
I would also definitely like to add more intractable elements in the future too.
I'm glad you like the game and I appreciate the support!
