At this point the development of this one is 'On Hold'. I'm currently doing another project in a Unity. It's a simple casual game for mobiles. Sound-related work is not yet started though, but I think soon enough I will have to start it, as project rapidly comes to a clear finish.
Oh, in that case if you need music I have this FREE 2D Platformer Music Pack. Perhaps it may be useful, it's 8 Bit / 16 Bit retro style. https://fictium-sound-design.itch.io/free-2d-platformer-pixel-music-pack
I'll be on the lookout for when you get back at developing your RPG game!
