Didn't see a topic for this yet but just downloaded the game on Android. It's a JRPG from Masato Kato who also worked on Chrono Trigger and there are some familiar aspects in this one. Been quite a bit of fun so far and doesn't seem to feature any need to really pay for anything as the game is basically handing you all the crystals you need for recruiting new characters plus companions that are recruited in the game storyline.
