You can play the game wich one the game itself took inspiration:
Sangeki Of Gear
Same vibe and customization is also
Breath of Fire and Iron and
Rhode's Fortress
I don't know about
Siren's Harp but ppl have also mentioned it (perhaps only the vibes tho).
Ppl also have said
Spin Around Sayla and his
sequel but I not remember playing these,
I might have a vague memory with the cover but perhaps I'm thinking about another game that was kinda hardcore (hard fights and very rpg like) and I dropped it for this reason, idk i might check it out again.
- edit:
Nope, it wasn't the same game I was thinking, well going to play it xD
Also, is not exactly the same but is a great game
Fountain of Mana, unfortunately it got abandoned from the dev..
(Worth check it out anyway, it does have a lot of hours of gameplay)
