I finished the game and must say very cool game idea. I had a lot of fun playing it. I wish there was music though.
Also i noticed a big number showing up. Maybe make that counting down? For example you start at 1 Million something and every time one of the player characters dies the number is reduced by one. Gives the game some kind of urgency not to die too often and also makes it feel like there are now less "you" in the multiverse. That could also be imbedded into the story, where the player tries to leave the facility, because he's scared that he will eventually be the last "you" in the multiverse.
Anyway. Great game, this has potential!
