My Teacher is an Alien
 

I remember playing the demo of an adventure game that was about a group of teens that were trying to save their friends from aliens while trying to find out who is an alien.
Anyone got a glue as to what it was called?

What kind of interface did this game use?

It varied if I recall right.
One part of the demo involved you playing as a kid with a slingshot sneaking through a vent shooting at rats while trying not to hit the walls of the vent so you won't get caught by the janitor.
And another one had you onboard an alien ship trying to save one of the kids by connecting these light paths to a door.

The name didn't stick in my mind.

Same here.
I gotta try and find the disc that have the demo on it.

I don't know what is funnier... The joke itself or the fact that you don't seem to get it. :p

Could you give us some idea of when you played it and the style of graphics?

Lets see.
The graphics were this animated yet realistic type of graphics with that the people look like people and not like some joke cartoon character.
And I can't exactly remember when I played it, but I'd guess maybe 9 or 10 years ago.

Alien Incident? My Teacher is an Alien?

Thats it!
My Teacher is an Alien is the game!
