1. It had a spooky house where a witch lived. She kidnapped a bunch of children then you had to play games and I think collect stuff to free each child. When you walked outside you walked through a maze of some sort. If you turned the wrong way you approached a spider on it's web.
2. I remember aliens (a green one and a purple one). I think one had 3 big tenticles on the front of it. There was a nerdy girl too (I think she slouched). You walked throughout a building and were searching for something.
