A Hole New World is an action game developed by Hidden Trap for the Nintendo Switch platform. In this game, the city is being invaded by monsters from the Upside Down World, and as the Potion Master, you must defeat evil all alone. There are no tutorials or "Easy Mode" to assist you, so you must rely on the help of Fäy, your companion fairy, and your potions.

The game features classic arcade-style gameplay, where you jump and shoot to fight enemies in your world and in the Upside Down World. You will face gigantic bosses and acquire their powers. The controls are simple, so you can focus on the game's challenge. There are five different worlds to explore in Story Mode, as well as Game+, Boss Rush Mode, Challenge Mode, and multiple endings. With over 30 different enemies, seven boss battles, and lots of secret characters to discover, there's plenty of content to keep you entertained.
