Well, hello everybody. I'm here because of Google

This is kind of desperate, but it has been in my head for some weeks.
I am looking for this game's name, but I just realized that I can not remember

But what I can do is to recall what the game looked like when I played, so I hope you guys can help me to figure out.
First, it was a Sega Dreamcast game:
1.- You were a teenager (maybe a pizza boy, because of the outfit, don't know).
2.- You were in some manor (or a castle, It was really big and gray)
3.- You could move only via D-pad and some buttons.
4.- In each room you had to evade the attacks of some ghouls, giant worms, a witch, some weird puppet, and that's all I remember because I could never go further in the game.
5.- Its animation was goofy, kind of Invader Zim-esque.
Please, help. This is kind of driving me nuts (not really, but I'd really apreciate your help).
Greets.
