Trapped

"Welcome Friend,
Enjoy the room ... it may be the last you ever see. If you are so clever that you think you may escape, here are the rules:
1. To get out, you must discover The Portal.
2. Be careful going through ...
3. If you don't get out ...
well, let's just say you won't be the only loser ... R."
And with that mysterious not before you, you realize you have no memory of where you were only minutes before, but now you are just in a strange room, one with no doors, no windows, no exit. The air feels stuffy, and as you set the note down, a bright purple light begins emitting from behind the cabinet doors. A slow, thrumming noise starts up, and you feel drawn to see what is inside ...

Rules:
The rules of the game are just that simple, find The Portal to escape each room. If you cannot find all the ways to escape, well, whoever the mysterious "R" is will certainly have the last laugh! But if you are clever enough, you just might go free to live another day. Are you ready?
