Who made your title theme?
A pixel artist who goes by the name of ConkerMich. His website is linked HERE. He works fast and is great with responding to messages.
Oh I was meaning to say who made your title music lol my bad.
That's more my fault for misunderstanding. lol. A lot of the music in the game (including the title theme) is made by Phil Hamilton. He has some game soundtracks for sale HERE.
Can his songs be used for commercial games?
Only one of the soundtracks. It can be purchased at the RPGMakerweb store.
Which one? I'm not sure what it would be.
