About Ninja Issen (忍者一閃)


「Ninja Issen」 is a retro-style ninja platformer that features a variety of hyper action, 1 vs. many battles, and dynamic boss fights. Paying homage to the ninja games of the classic 8-16 bit era, 「Ninja Issen」 is full of ninjas, robots, neon lights, and dark atmosphere that overwhelms the streets of the future metropolis.

You will be 「Kiba」, a rogue ninja who was falsely accused of assassinating the grand master of his clan. In his desperate fight to escape from other ninjas trying to avenge his crime, 「Kiba」 suddenly finds himself in the middle of the world he has never seen.

THE GAME


In 「Ninja Issen」, you will always encounter 1 vs. many battles in which you must use everything to survive. The enemies come in many types and designs, large in number and ready to strike wherever you go.

Fortunately, 「Kiba」 is a seasoned and skillful ninja who can overcome dangers ahead of him. Use 「Kiba」's weapons and abilities to cut down rushing enemies, and explore the future metropolis.

• KATANA - 「Kiba」's main weapon which is highly effective in close combat.

• SHURIKEN - Used for long-range attack and to deflect enemy projectile.

• TELEPORT - 「Kiba」 can teleport by throwing his katana to the spot he wishes to reach. Use it to jump between high structures and pass through traps like a pro ninja.

Combine 「Kiba」's weapons and ninja skills to make your own fighting style!


BOSS BATTLE



Each stage will have a boss that features unique patterns and gimmicks. As 「Kiba」, you will need to find out how to withstand their threatening attacks, and achieve victory in the end.

Sometimes the battle moves on to Phase 2 when the boss' HP reaches below a certain point. In Phase 2, the boss will show new and fiercer attack patterns. Destroying parts may also change the pattern of the boss.

✦ AI summary

Players praise the game's stylish artwork, satisfying soundtrack, and smooth, well-balanced gameplay that respects players with generous checkpoints. However, multiple reviewers criticize unclear visual hierarchy that makes it hard to distinguish foreground from background and projectiles, problematic camera framing that causes blind jumps and undeserved deaths, and boss encounters that feel underdesigned with overly telegraphed or easily exploitable patterns. The game shows promise as a retro-style action platformer but needs significant polish in presentation and level design to match its ae

AWESOME OST. (as good as video on store page) Great pixel art and style. Smooth. Balanced (not too punishing, not too easy) I thought the full price might have been a bit high but it's perfect where it stands. Some hitboxes seem larger or last longer than they look, but most are done well. edit: Forgot to mention the camera isn't the best for placement but it's more cinematic.

Ninja Issen is a stylish, fast-paced action platformer developed by ASTEROID-J and published by CFK Co., Ltd., and it immediately distinguishes itself through its striking retro-futuristic identity. Set in a world that blends traditional shinobi mysticism with neon-lit cyberpunk machinery, the game follows a lone ninja thrust into a violent technological uprising. Instead of relying on lengthy exposition, the story unfolds through atmosphere—ominous stage design, looming mechanical threats, and fleeting character interactions that hint at a fractured society struggling to reconcile ancient warrior ideals with cold industrial logic. It’s the kind of narrative setup that doesn’t overwhelm players with lore, but provides enough thematic tension to give each level meaning and mood. The gameplay focuses primarily on high-speed traversal and skill-based combat, echoing classic 16-bit action platformers while adding modern responsiveness and polish. Movement feels slick and empowering—wall running, double jumps, air dashes, and quick evasive maneuvers allow players to maintain momentum, and mastering that mobility becomes just as important as learning enemy attack patterns. Combat is a b…

Sadly I cannot recommend this Ninja game at all. It's an 8-Bit style retro game which is heavily based of the old classics from the Nes/Master System era. Whilst the comic sections are nice I found the rest of the game very lacking in style, polish, substance or fun. It's an OK game but in all honesty I could recommend so many other better ninja games than this one. A full review can be seen here : https://youtu.be/gZX8qLMeguk?si=EphaZqWwZw-Sko-l

Fun little action platformer (similar to some classics of the genre), with some nice ideas, but on the easier side. The game is very forgiving , has a lot of checkpoints and isn't punishing at all. While the overall art and spritework is nice, I have some issues with it in several levels. Sometimes there is to much on sceen, it's not clear what background, forground and what are projectiles. Also the bosses while most are very easy because you can just spam your specials, design wise most need better telegraphing. Like that you can design more interesting fights. And the camera... while it received an update with the latest patch, there still a bunch of blind jumps. I like the game for what it is. If you get it cheap and can live with some of the issues, you can have fun for 2-3 hours (+ hard mode, time trails for individuell levels etc). Bonus: The game still recieves updates, almost 2 years after the release. Support your indie dev.

This game needs an art director really bad, it's hard to tell what's a wall and what's background. The mechanics feel really stiff and have no juice. The screen scrolling is messed up and results in a lot of needless damage and deaths just because you can't see anything. That said, there's 60% of a great game here. I wish they'd make it 100% but I don't think that's going to happen.

Clunky controls, poor iconography, poor level design
