I got the master of disguise ending but I got no achievement. On my second run, I charged at the man, gunned the door, and when I got inside the disguised scene played on top of the current one, I also had the options from the previous run. On the title screen I now have 4 scenes happening at once. the title screen, the chocolate, the final choices in the master of disguise route, and the up choice at the start of the game. TL;DR, there are a lot of bugs. Decent as a concept, not very good in practice, at least at the time of writing this.
