Endless mansion

Intro This is an interactive "choose your own adventure" game. You and Melissa lost a bet and you have to spend the night in a deserted mansion. After entering building, the two of you start exploring. But something is wrong. Walls look older and cracked, the furniture is different, and you keep hearing eerie sounds. It is also impossible to see the outside world through windows, you see only darkness. But more importantly, the building just keeps on going. There is no end to its hallways. You try to leave but the doors won't open and windows won't break.
