Greetings Sami,
Thank you for getting back to me, and your project looks very intriguing indeed. I like the idea of a fantasy metroidvania with environmental storytelling, and having a developer with cinematic background is an additional bonus.
I would love to hear more details regarding the antagonist role you have in mind, as well as the general tone and atmosphere. Projects like this are something I enjoy participating in, as a voice actor.
To give you an insight into what I bring to the table, I am a professional voice actor who worked on many video games, animation projects, and horror movies. I love voicing intense, emotionally heavy, or morally complex characters, so your game seems like the perfect fit.
