Ember Lab has the Anniversary Update 2.02 to Ken: Bridge of Spirits released, which includes new features and content.
As mentioned previously, this makes the New Game Plus option available. This allows players who have completed the game once to restart their journey with all their previously unlocked abilities, upgrades, outfits, items, etc., to face redesigned and more challenging encounters.
“We hope players enjoy replaying or continuing to play Kena: Bridge of Spirits with these constant reminders of the special characters who help Kena on her journey as a spirit guide. Even though we've tested them, every time we play with a different outfit, we're reminded of helping Beni and Saiya find their brother for the first time, or learning how to guide the bow from Rusu.”

Furthermore, the Spirit Guide Trials are now available, a new game mode accessible via the Mask Shrine. This mode allows players to prove themselves on an obstacle course, in wave defense, and with boss reflexes to earn new outfits. Achieving bonus objectives in each trial grants additional color variations of each outfit, as well as some unique Charmstones. There is also an exclusive new outfit for owners of the Deluxe Edition.
The "Charmstones" can be individually equipped and include unique collectibles, each offering different adjustments to Kena's stats and abilities.
The update is available for free as promised. Ember Lab has published the full patch notes. here detained.
