A Manual is built in, this game is better for a trial-and-error style, if you need help, read until you find your result, then click the green flag.
There are minor flashing lights, epilepsy warning. This game has some disturbing visuals, 9+ There are minor amounts of blood, sharp teeth, and it can get very dark. Beta versions can be found on my profile. I'm hoping to add multiplayer in the future.
