Devil Island copies Konami's Japan-exclusive NES game, Getsu Fuuma Den, with its gameplay. The game's aesthetics are styled after the Castlevania franchise, also by Konami. Much like Castlevania, the player's default weapon is a whip, except it can be held down for rapid fire. Items can be bought and used in-game by pausing and selecting with the A and B buttons, which are needed to progress in some places. The player must also find and defeat guardian bosses in order to proceed. The game offers unlimited continues.
Devil Island shows a few signs of being developed by Vast Fame. The main evidence is the Mega Man V sound engine. In addition, this game has also appeared on several Vast Fame-licensed multicarts alongside confirmed Vast Fame games such as Shi Kong Xing Shou.
The opening cutscenes are clearly stolen from various SNES games.
- Batoru Raiden - A group of red-eyed robed people approaching a rock dragon's mouth.
- Castlevania: Dracula X - An upwards shooting beam of light and a group of zombified villagers.
- Demon's Crest - A green dragon that briefly appears just before the narration text.
- The Li Cheng version, Lord of the Rings 3, is a hack of the regular game. On top of having a new intro/title the player sprites are changed, the map's removed making the player play through (seemingly new) levels in a linear fashion, and the levels play fewer music tracks.
