The premise is that there are four main characters (a normal guy, his girlfriend, a cop?, a businessman) who wake up in a burning building. In each short scenario, you get to choose who lives (you save them by blocking the fire's path) and who dies (basically, the opposite). You get a different ending depending on the character(s) who live after three scenarios. Some endings feature hopeless situations where all characters are impossible to save at the second scenario. Like some VNs and games, when you view all the endings...
the game opens differently and everyone remembers what happened in every story branch a la Zero Escape. This opens up a new branch where you are able to save EVERYONE and reach the golden ending.
Anyone knows this game? It's basically one of those hidden gems I would want to recommend to everyone but I just can't remember the name.
