Unnamed NSFW Metroidvania: IDFK!

What happens when an inexperienced game dev who's never fully finished a single project decides to undertake a hentai game with more features and scope than they ever have a hope of achieving?

I don't fucking know, this weird metroidvania/bullet hell/hentai game I guess? 

Project is still in the VERY early stages, and I'm still learning Godot after switching from Unity, and because I run a full time job (likely because I can't finish a single project and make it as a *real* dev).
