Evaluation
Onikira: Demon Killer launched on August 27, 2015 after an Early Access period during which the developer actively added levels, enemies, moves, and systems. The launch post on August 27, 2015 marked the completion of the game, with the developer explicitly stating "it's done" and signing off — thanking early access players, publishers, and their families with the clear tone of a project concluded. A single follow-up patch was released on September 4, 2015 addressing performance issues, achievements, and bugs reported at launch. That patch is the last recorded developer communication. All DLC (a soundtrack and bonus content pack, both released November 14, 2014) shipped during Early Access. No new DLC has been listed since. No post-launch roadmap, expansion announcements, or further developer communications exist. The game launched as a complete, finite product and has received no content updates since the September 2015 polish patch.

About this game

Developed by Irish-based indie, Digital Furnace Games, Onikira: Demon Killer is an awesome side-scrolling, 2D beat’em-up set in fantasy feudal Japan. As Yamazaki Jiro, a lone samurai, players battle to prevent the forces of the Japanese underworld, Yomi, from consuming the land of the living.
Onikira: Demon Killer blends together complex deep fighting mechanics usually found in traditional 3D beat-em’ups, like Ninja Gaiden or Bayonetta and merges them with classic 2D platform-game mechanics. Onikira’s expressive fighting system enables players to engage in whichever way suits them best. Some players will prefer to go toe-to toe with heavy weapons and mash buttons while others will opt for a ranged game style, avoiding heavy melee encounters. Try launching an enemy into the air, wall jumping to position yourself above them then Katana Slaming them into the ground. Switch weapons to the Naginata and use the Naginata Lift and air dash moves to stay in the air and off crumbling platforms, while pulling enemies up to you to be dispatched in mid-air. Whip out your grappling hook to grapple between platforms, across chasms or fiery pits, all the while fending off enemies.
Onikira: Demon Killer boasts seven challenging areas and players can express themselves with over forty uber-cool moves, using four devastating weapons. Each level is littered with foul demons that players must dispatch back to the underworld and players must also face two mini-bosses and two epic mega bosses. Every level is crammed full of environmental aids to help the player in combat encounters. Slice the support pillars off a building and watch it crush your enemies as it collapses, or use your moves to fling enemies into spikes, pits, or the path of moving deadly objects. Be careful though, as dropping a building on your own head is known to cause sadness!

Unique high-level combat – Onikira mixes 2D platform game elements into the combat system to make something special. Moving platforms, wall jumping, wall running and grappling all serve to make for dynamic and emergent combat encounters.
Seven Areas – the narrative unfolds over highly polished and gorgeous hand-painted levels featuring rain drenched villages, destroyed opulent cities, mountaintop locations and an erupting volcano.
Master unique weapons – Each weapon - sword, tetsubo, naginata or arm blades - has multiple unlockable moves which can result in massive combo chains when moves are strung together. Combo chains turn directly into score multipliers.
Responsive and Expressive Combat System – players are rewarded for strategic and skill-based fighting. Play flows naturally from move to move, allowing the player to create new combos that haven’t been designed explicitly by the developers.
Soul Shop – souls are the currency of Onikira. Use them to revive your health and trade them. At certain points inside each level, the player will find rifts into Yomi where benevolent spirits will trade moves for collected souls.
Challenge Arenas – players complete combat related challenges and improve their score and skill to gain achievements. The arenas are fully integrated into Steam’s online leaderboards.
Specific enemy types – with their own unique vulnerabilities, every enemy emphasises a particular fighting style, like a floating, possessed Mempo mask that encourages the use of air game or a monstrously twisted high-ranking samurai, where hit and run tactics are the best way to stay alive.
