Arranger -> Free (Different publisher, might want to dl even if you own it)
I've had my eyes on this game for awhile, but never got around to buying it. It won't show as a price drop in an app tracker because this is by a different developer. It was published by Ayopia...if you own this, I would DL this version...apps that already exist but are released under a different publisher/developer often times means the rights have changed hands, and you may not be able to re-download from Ayopia. I'm not sure, but this is often a sign of that. The dev usually makes it free for a day or so so that previous purchasers have a chance to get it without paying again.
