You have to find your way out through one of the doors. There are 14 possible endings, so be sure to explore them all. This shall be rated T for safety since there are some intense scenes.
I thought it was a very nice little game. I think there should be more choices in the hallways, not just about the doors. It felt like there was only 3 things that could happen, and no room for variation. That said, it was very detailed and quite enjoyable. The writing was detailed, yet to the point, and I enjoyed playing the game through multiple times to try and find the different endings. The game was short enough that this didn't feel like a chore, and the endings were varied enough that they didn't feel repetitive. All in all, nice job.
