I really like how polished it already is. My native language is Spanish, so I haven’t been able to fully dive into it, but it’s not your fault at all, and it’s not that it needs to be translated into Spanish. In fact, I think it might even be better this way, as I can give you a different kind of perspective.
I think the first room scene is a bit saturated , lighting, effects, ambient sound, etc. Some players might like it, others might not. Since it’s the first playable section, it might need a softer redesign.
I really, really miss the sound of the player’s footsteps, even if they were very quiet.
Other than that, it might sound silly, but it reminds me of The Addams Family game for the SNES. It’s a great project, and you can tell there’s a piece of your soul in it. Keep going like this.
