I wanted to address a few things myself.
1. I've done that already, and will probably implement the Exp. Share for people who want an easier game experience.
2. I've been reworking some of the earlier game events so that's likely to change.
3. The trainer house allows you to battle repetitively so as not to be forced to "grind" in the wild. It's there to make it easier for people who want spend time leveling up their Pokemon. As of now the trainers don't get any stronger, however there are several similar battle facilities spread out throughout the region with stronger Pokemon to battle against.
Thank you for your support!
I don't have the time to always make promotional material, but here are a few more gifs to keep you interested:
I've gone back and redid most of the Mr. DS base animations, so expect a fresh experience when battling!
