First of all, thank you very much!
It's always nice to hear it when someone enjoys my work.
In regards to your question, I'll say this:
I don't believe in publicly releasing game assets, as it's just not something I do.
However, if you were to rip said assets yourself, or go and find them, then that's entirely up to you.
I make the games, and anything after that I have nothing to do with,
I absolutely love all of your games... I haven't been able to play them myself, because I use a Mac since I develop software and need a Unix environment (and I just don't like Windows, especially since 8) but I've watched ManlyBadassHero play through them all on YouTube and they are easily amongst my favourite horror games... the unique but consistent art style and your ideas are great!
