When a kid is abandoned by his parents and left alone for a day, they start to go insane and start seeing creatures of their own nightmares. Driven by sleep deprivation, they must manage their energy and take quick naps while surviving against the never ending threats to survive only one night. Only One night is a Fnaf-Like game with Rogue-Like elements such as enemy scaling and powerups. Instead of the usual night formula the game is split into many fast paced hours, and you must manage your energy by taking naps which leave you vulnerable. Every hour you can get a powerup which can be as small as a stat up or the ability to parry the nightmares. The game is inspired by many Rogue-likes such as Binding of Isaac, Fnaf, and it's many Fan Games, such as One More Night (Roblox) and Too Many Nights. The game was made previously for a Game jam with the theme "Only One", and was originally released with a v1 demo. The game has been polished ever since, with many new features such as enhanced music, sounds, sprites, and a more refined gameplay loop.
