Push Square
3.0The entire game is very short, lasting about 15 minutes a run, consisting of just a handful of puzzle rooms along branching paths before you're presented with one of several endings. This means that often you'll have to repeat paths and redo puzzles you know the solutions to just to reach a single new challenge. Should you fail a puzzle, it'll activate a torture scene in which both the girl and you meet an untimely demise.
