The plot is as follows: Jake, the protagonist, has become trapped in his school, which has been plunged into darkness. Dangerous creatures lurk in the darkness, and Jake must use the various light sources around to safely navigate a path to the exit. However, turning on too many things at once and filling the light meter at the top will cause a fuse to blow, sending you back to the start of the room.
Occasionally a room will have a ringing phone; making it to the phone and answering it before it stops ringing will let you listen to a phone call from Jake's girlfriend, Rachael, as she works to escape from the school as well.
In October 2015, a version of the game with a different, "cutesier" art style but the same characters and basic gameplay was released for iOS and Android, and this version was also released for PC through Steam on February 21, 2017.
With the disabling of adding/purchasing Wii Points on March 26, 2018 followed by the complete closure of the Wii Shop Channel on January 30, 2019, the original game is no longer available for download.
This game provides examples of:
- Another Side, Another Story: Beating the game as Jake will allow you to play through again as Rachael. Her levels are exactly the same, but the phone calls she gets are from Jake. It's implied that both stories take place at roughly the same time.
- Brats with Slingshots: Jake can use his to break windows to provide light, or to destroy inconvenient light sources like extra computers from a distance to manage power consumption.
- Creator Cameo: Jake's voice is provided by Voldi Way, the founder and CEO of WayForward.
- Dark Is Not Evil: Word of God states that the choice in making Jake an Emo Teen was to invoke this trope. In Dark Mode, Jake and Rachael are dark versions of themselves (complete with Glowing Eyes of Doom), further playing this trope.
- Darkness = Death: Invoked. Stepping into or being caught in any unlit area is instant death.
- Death Is a Slap on the Wrist: Even in Dark mode, you have unlimited lives, and dying only sends you back to the start of the room.
- Emo Teen: Jake. According to the developers, he was deliberately designed as this to invoke the irony of the type of person associated with darkness literally bringing light to his school.
- Fade to White: If the player uses too much energy, the screen will fade to white as the generator breaks, leaving Jake/Rachael to be consumed by the darkness.
- Idiosyncratic Difficulty Levels: "Light" (easy) and "Dark" (hard). The rooms stay the same, but in Dark Mode, Jake (or Rachael) appears as a silhouette, and all light sources will slowly dim once turned on (and cannot be re-turned on once they're off entirely), so every level becomes a Timed Mission after you've made your first move.
- Light 'em Up: Jake and Rachael take down the school staff by manipulating the room to shine light sources in their faces.
- Multiple Endings: Each character has a good ending and a bad ending. Listening to all the phone calls in the game will get you the good ending.
- One-Hit-Point Wonder: Jake doesn't even have a health bar. As soon as any part of him touches the darkness, he's done for.
- Puzzle Boss: Every boss is this, requiring you to use different strategies to damage them with the light.
- Ten-Second Flashlight: You have one of these at the start of every room, and it's vital for scoping out the level for what you have to do. It depletes in 30-ish seconds of continuous use, but you can recharge it by shaking the Wii-mote.
- Throw Down the Bomblet: Cherry bombs work similarly to the slingshot, but with Splash Damage. In certain rooms, you have to make use of that to break more than one window at once. They also generate a quick flash of light, which is a vital mechanic for certain boss fights.
- Timed Mission: In Dark mode, unlocked by beating the game once, all light sources will start to dim when activated, and can't be used again after they die out. After the first move, you have to move fast to get through the room safely.
