Best website ever. After finding this site earlier today, I see no need for any others. There are hundreds of thousands of samples on this site and the vast majority are stupidly high quality.
Just posting this to let you know that I'm really focusing on the sound effects in this game. You know that deep bass you get before a large crack of lightning? That rumbling, moaning sound that echoes around (and within) your room? These samples get it perfectly. I actually got intimidated by some of the storm sound effects on this site- their rumbling bass and cracks of lightning are genuinely scary, and I can't wait to implement them into this game. Let's just say, you don't want to be caught in one of these storms at night time.
Oh, and as for the game- it's in a working state. If I wanted to right now I could make the entire world, as large as I'd like, and it would be able to remember your position and all level changes that occur. It's nice that it all does this automatically, it was a right nightmare trying to link up each of the levels manually.
