Ninja Arena

Ninja Arena is a browser RPG by dd34sz focused on choosing skills and preparing a ninja for automatic battles. Five elemental characters and companion pets provide different starting builds. The game is in testing and includes a guest mode that does not require an account.

Choose an element and prepare a skill loadout

The five starting elements are fire, water, earth, wind, and lightning. Each character has different stats and abilities: Kaen, for example, emphasizes fire attacks and critical hits. Companion pets add another layer to the build. Before a stage, players can inspect the enemy, weather, and equipped skills.

Combat runs automatically, so preparation takes priority over manually selecting every attack. The battle screen tracks HP, chakra, status effects, and remaining turns. The appeal is in setting up a character and seeing how that preparation performs.

What we actually played

GameSlash tested v67 on 20 October 2026 in offline guest mode, selected Kaen and the Homura pet, used the starting skill setup, and completed stage 1-1. That run ended in victory after eight turns and advanced the character to level 2. This verifies the opening gameplay loop, not the balance of the entire game.

How to start and keep your save

Open Ninja Arena on itch.io, press Run game, and select guest play. Offline progress is stored in the same browser, so clearing site data or changing devices may lose it. The official page lists desktop and mobile-browser support and recommends landscape orientation on phones.

The current game also offers an account option for online saves. We did not sign in or test cross-device progress, online play, or duels during this session.
