Retla has stepped into the Eternal Palace Sakura, and getting back out is going to take some work. Shochiku Games, the games division of Shochiku Co., Ltd., has launched the 3D action roguelite from Japanese indie studio Denneko Yuugi, which arrived worldwide on Steam on Wednesday 4 November 2026 and is now also available on Nintendo Switch.
The game follows cat-eared heroine Retla Stlutin, who travels to Ouran, a land in the Far East, after hearing rumours of a mysterious tower that stretches endlessly into the sky. After many hardships she reaches the palace, only to become trapped the moment she steps inside. From there, the aim is to fight through hordes of enemies, collect treasures and see how far into the palace she can go.
Retla is a dark-skinned heroine with a cat-eared hood and twin blades, and combat is built around chaining combos with simple button presses. Up to four special abilities, called Arts, can be equipped at once, along with an ultimate technique called Over Arts. Bosses wait on the deeper floors, and Shochiku says the combat is designed so that players new to action games can also enjoy it.
The dungeon is procedurally generated and filled with drifting cherry blossoms. Players can create their own builds by combining more than 50 power-up items called Attributes, while managing Mugen Depth, which adds debuffs and stronger enemies. Permanent upgrades can be unlocked between runs, and Endless Mode is available for those who want to push further.
Eternal Palace Sakura is available now on Steam and the Nintendo eShop.
