Slime-san: Blackbird's Kraken

My first instinct with Blackbird's Kraken was to treat it as a bonus round, something to tack on after finishing the base Slime-san. That framing is wrong, and it undersells what Fabraz actually built here. This is a standalone, fully independent campaign that swaps the original's wintry worm-gut setting for a tropical kraken's innards, and the change in venue carries real design weight. The hostility of being trapped inside a mythical sea monster seeps into every level layout, and the difficulty curve reflects that shift honestly rather than just dressing existing content in new colours. The mechanics you carry over from the original, quick deaths followed by instant level restarts, remain the foundation. What Blackbird's Kraken adds on top is genuinely fresh: a pilotable submarine that changes how you think about movement, suction cups that cling you to surfaces in ways the original never asked you to consider, and acid bubbles that turn already narrow windows of survival into something even tighter. Bananas replace apples as the collectable currency, and they are almost always positioned so that grabbing them requires you to either disturb dormant enemies or linger long enough that the kraken's insta-kill stomach acid becomes a genuine threat. The risk calculus per room is sharper than anything in the base game. Each of the 25 levels (plus 25 New Game Plus variants) keeps the four-screen structure the original established, and each one ships with its own distinct theme and gimmick, so the hundred-plus platforming scenarios rarely recycle the same spatial logic twice. Target mode challenges, online leaderboards with an independent speedrunning mode, 200 bananas to spend across clothing and furniture shops, and a customisable house round out the meta-loop for players who want to sink time beyond the campaign itself. Where the game earns its one honest warning is in that opening difficulty spike. Reviewers who came in cold, without prior Slime-san mileage, consistently flagged the early stages as punishing in a way that feels less like fair challenge and more like a cold shoulder. The in-depth tutorial tries to compensate, but the raw muscle memory required to survive even the first few levels assumes familiarity with Slime-san's peculiar rhythm of dashing, shrinking, and re-timing jumps mid-air. If you have not played the original, the smart move is to start there. If you have, Blackbird's Kraken will feel like the sequel the original deserved: same tight controls, the same immediate-respawn philosophy that keeps frustration from curdling into resentment, and a chiptune soundtrack that earns its own moment of attention. The five-colour palette visual style still does things that should not be possible at that resolution, and the tropical aesthetic gives the whole expansion a sun-bleached, slightly menacing glow that distinguishes it from its predecessor without breaking the series' hand-crafted identity. For the completionist crowd, there is a customisable house to furnish, secret characters to find, a boss fight against the Kraken itself, and enough unlockable play styles and outfits to justify multiple runs. For the speedrunner contingent, online leaderboards with per-level and full-run timing give the whole thing a competitive spine. Blackbird's Kraken knows exactly what it is and ends when it should, which is rarer than it sounds in the expansion space. Fabraz did not pad this out to justify a price point. They made more Slime-san, properly, which is the highest compliment I can give a piece of additional content.
