A collection of Halloween-themed games, along with their source codes, offers a rich resource for entertainment, learning game development, or experimenting with cheats. These games are generally created in a short period for game jams, ensuring focused and engaging gameplay. Highlights include Chamber, a game about escaping a loop by exterminating enemies; Paralunar, a fast-paced ghost-hunting game set on a haunted moon castle; and From the Shadows, a cooperative puzzle platformer centered on light and shadow. Other notable mentions are Q1K3, a minimalist Quake reimagining, and Landlord, a low-resolution dungeon crawler. Each game features unique aspects such as the elevator-themed Hellevator and Chess Hellevator, or the reverse-horror game Deviant. These games provide entertainment while also serving as examples for aspiring developers to study and modify, with cheat codes available for those inclined to tweak gameplay further.
