Kureiji Ollie Becomes a Ninja in This High-Difficulty Action Game
Ollie Ninja Slash is a high-difficulty platform action game starring Kureiji Ollie, a talent affiliated with hololive Indonesia.
Players take on the role of "Ninja Ollie" and venture through a series of dangerous stages in pursuit of a stolen scroll.
Using jumps and slashes, players cut through crystals floating in midair while moving through each stage, avoiding enemies and obstacles such as spikes, and aiming to reach the scroll hidden deep within.
The game is scheduled for release on Steam on Friday, September 18, 2026. Wishlist registration is currently open on the Steam store page.

Simple Controls, More Than 30 High-Difficulty Stages
Using left and right movement, jumps, and slashes, players make their way through more than 30 stages in search of the scroll.
While the controls are simple, enemies and obstacles such as spikes are placed throughout, and a single split-second misjudgment can end the game.
It's a high-difficulty action game where players gradually improve as they memorize routes and timing. The sense of accomplishment that comes from clearing a stage after repeated trial and error is part of the experience.
