Some cool ideas here, and I love the model for the failed specimens. But the level design has me pretty perplexed, I stopped playing when at one point (after catapulting the failed guy forward) i dropped back to the start and was unable to progress? I guess maybe I was supposed to have figured out the code by then but I had not. There also seems to be something weird with your buttons, I think they might hold doors open longer the longer you stand on them? at any rate I was able to skip stuff if I wanted by standing on them for a long time and then just running through the door before it closed.
