this game is a very early version of what could be a Metroidvania with RPG mechanics. And although it is a prototype it is playable, at least from what is advanced. The game currently features two bosses and tells a bit of backstory. It should be noted that the game is intended for mobile platforms (for now) and is only available for android. I would really like you to try it and give your opinion.
