Kamui is the first title released in the "Tales of Alltynex" trilogy, a trio of 2d shoot em ups focusing on cinematic presentation, offbeat gameplay mechanics, and a strange and melancholy storyline about planetary warfare and rogue super computers.
In Kamui, players have access to a standard machine gun for destroying hordes of small enemies, a homing attack which only hits distant enemies attacking from the background, and a powerful beam weapon that focuses damage on a single target and nullifies enemy fire. The last two weapons are dependent on a recharging energy meter that must be carefully managed, because running out of energy can result in being overwhelmed. Destroying enemies with a charged homing attack also awards greater points, but requires players to leave dangerous enemies alive for longer and find perfect timings to blast them all, forcing mastery of the mechanics to achieve high scores.
I find these mechanics give Kamui a sense of chaos. Not only do players need to dodge and shoot the usual enemy formations and attack patterns found in shoot em ups, but they also need to be careful of enemies in the background and simoultaneously juggle three weapons with precise use. Beyond the mechanics, the game's actual execution of stage and boss design is refreshingly unique. Kamui has a slightly larger hitbox than most bullet hell shooters and an emphasis on agressive enemies and bosses with quirky attacks that go beyond the usual bullet ballets of the genre. The chaos and agression combine to give Kamui a very visceral feel.
There are drawbacks to Kamui's design choices, though. At times, the bullet cancelling beam dominates the game a bit too much, turning evasion into a matter of simple timing and placement instead of complex manuevering, reflex, or strategy. Playing for score alleviates this somewhat, forcing you to hold off on cancelling some attacks, but I still wish pure survival play wasn't as simplistic. I also don't like the vast amount of health players are given. The difficulty is balanced around it, but the sheer amount of life points the player has means that no matter how bad you do on any one stage, you're pretty much guaranteed not to die till at least the next stage, removing some of the tension from the game's first half.
However, when its playstyle clicks in the end game, Kamui truly shines. The last three stages offer one of the most intense and memorable climaxes in the genre, and the intensely visceral action throughout generally make up for some minor issues. For those looking for something a little different, Kamui is an excellent change of pace from shooting game norms.
