I fucking love this genre. The whole creepy other universe Cthulu type deal. I wish there were more games and movies like this.
The atmosphere is spectacular, the music fits it perfectly, and I love that it looks like an SNES game. I thought that fact really made it interesting, going along with the theme.
I did have one problem, but it's probably because I'm just not great at video games sometimes. But the one-hit death really bothered me sometimes, especially when I was getting so into the game but then this one fucking enemy would keep killing me because I couldn't get the gun back. Maybe if you didn't lose the weapon when you died... that would be nice.
Otherwise. Please make more.
