I think Pillar Chase 2 is a great idea. Plus, if The Stricken returns (I hope he does because he's my favorite monster in Pillar Chase. If he gets scrapped permanently, I will quit Pillar Chase forever), Frankendoll would be a skin for The Stricken. Plus, I don't care if they ask for my permission. They can use Frankendoll if they want to (if The Stricken returns).
I don't know about collaborating with Outcome Memories. If the devs want to use Frankendoll, they'll need my permission first. I'll think about it, but if they get away with using Frankendoll without my permission, or create a bootleg, they will be in HUGE trouble.
