overall 8.8/10 (based of personal opinions)
the gameplay is very simple yet fun, with 4 enemies and wasd/space controls, and the overpowered lantern, 8/10
the art style of bad piggy is interesting and DOOM-like, and the changing viewpoints of winding halls is interesting, 10/10
the story is short and sweet yet very deep, and being told through the notes and dialogue, it gives a great storytelling, 9/10
the soundtrack is ominous, though most of the game is silent, which adds to the atmosphere, 7/10
other features: being a web port, it can be played on most operating systems and hardware easily, also I'm biased about bad piggy as he is one of my favorite devs, 10/10
