This OST right here HAS to be in a game! I'm really blown away by what you did! The area exploration check was so effective in creative ambience that I actually felt like I was playing a JRPG. The battle theme also had an obvious Chrono Trigger influence, yet it was so unique i can't say it sounds like it. Perfect battle theme!
The craziest thing is I listened before reading your description, and already knew that this was for a JRPG with some influence from Chrono Trigger, so you really did everything you had to do to convey what you wanted clearly. This is perfection right here!
