It Hits the Nostalgia Nerve
It’s rare that a demo taps perfectly into my GBA-era sweet spot like Tako no Himitsu: Ocean of Secrets does. From the moment the demo boots on Steam, chunky sprites, garish palettes, and an oceanic soundtrack drenched in Golden Sun vibes had me dusting off my old wireless controller for a one-hour marathon. By the end, my pixel-adventurer’s heart was pounding just as hard as when I first discovered turn-based Djinn summons.
Key Takeaways
- Visually arresting pixel art: Bold, caricatured characters and environments recalling GBA cart art.
- Twin prologues: Choose a reflective scholar or a sword-wielding warrior, each with unique pacing and tutorials.
- Octopus companion system: Stat-boosting critters with elemental sigils, reminiscent of Chao pets.
- Varied puzzles and platforming: From block-pushing shrines to wind-tunnel leaps, plus timed lever challenges.
- Immersive soundtrack: Motoi Sakuraba and Masanori Hikichi–inspired compositions that peak at heroic crescendos.
- Controller-first design: Gamepad feels native; keyboard support still needs refinement.
- Narrative hooks: Sea-god lore, phantom islands, and the secret Heart of the Deep.
First Impressions – A GBA Flashback
The demo’s UI greets you with oversized menu boxes and chunky text that feels impeccably pixelated. Menus slide in with playful elasticity, and character portraits pop against bold backgrounds. Dialogue carries dry wit—villagers gossip about “tentacled folk” pilfering nets, while guards grumble about missing bait—striking a perfect tone that blends earnest JRPG world-building with light zingers.

Two Prologues, Two Tempos
Early on you pick between two protagonists. The scholar’s sequence unfolds in a pastel-watercolor hamlet, rich with NPC chatter that seeds ocean deity myths and hidden temple clues. Each dialogue choice here affects villagers’ attitudes and unlocks alternate side quests.
Switch to the warrior path and you’re immediately thrust into fast-paced combat. Tight combos, dodge rolls, and a momentum-driven dash evoke Metroidvania flair, offering a stark contrast to the scholar’s methodical exploration. Both routes reveal different tutorial segments and world lore, making back-to-back replays feel like distinct mini-demos.

Combat Depth & Character Progression
Far from button-mashing, combat demands timing and strategic pet deployment. Early on, a fire-sigil octopus applies burn effects on light-attack chains, while a healing octopus provides passive regeneration mid-fight. Enemies telegraph attacks just enough to reward well-timed dodge-roll invincibility frames. Gear drops from slimes and sea-raiders come with simple affixes (+5 Attack, +3 Magic Speed), hinting at deeper RPG layering in the full release.
The demo also teases a branching skill tree featuring elemental affinities, passive buffs, and advanced pet abilities—though only preliminary nodes are available. Bosses remain locked in the demo, but I faced a mini-boss pirate captain whose multi-stage moveset underscored how tactical layering could elevate later encounters.

Puzzles & Platforming Showcase
Exploration leads to a cliffside shrine where block-pushing puzzles on pressure plates intertwine with shifting sand hazards. A wind-swept canyon later tests your reflexes as gusts lift you onto drifting platforms and collapsing tiles punish hesitation. Collision detection can feel a tad generous in these sections; tighter hitboxes would transform certain leaps from trial-and-error to skill-based triumphs.
Story & World-Building Glimpse
The narrative foundation is concise but compelling. An archipelago shaped by feuding sea deities, murky legends of a lost Heart of the Deep, and rival treasure hunters all promise a sprawling tale. In-dungeon murals depict a cataclysmic ocean god war, while merchant ledgers reference phantom isles that surface only during storms—enough to stoke my curiosity without overwhelming the demo.
Developer Profile & Release Roadmap
Developed by CometTentacle Games, a four-person indie team founded in 2018, Tako no Himitsu marries collective JRPG obsession with modern design. After unveiling the demo during the Summer Next Fest 2024, the studio plans a closed beta in early 2025, targeting a Q4 2025 full launch on PC and Steam Deck. Their pipeline includes expanded side quests, a co-op Octopus Arena mode, and robust accessibility options.

Performance & Platform Notes
On a mid-range PC (Intel i5-11400, RTX 3060 Mobile), the demo ran at a locked 60 FPS with sub-three-second area loads. On Steam Deck, it hovered around 45-55 FPS at 720p; the upcoming Vulkan build promises performance optimizations. Controller mapping felt seamless, though keyboard support needs customizable keybinds and colorblind palettes.
GBA Comparisons: Golden Sun & Sword of Mana
Tako no Himitsu wears its inspirations on its sleeve. Its overworld palettes and expansive harmonic themes echo Golden Sun, while side-scroll combat’s fluid combos recall Sword of Mana. The deliberate pixel choppiness feels less like a flaw and more like a stylistic homage to cartridge generation limits.
Mechanically, the demo isn’t as polished as those classics yet, but its affectionate nods and solid core systems promise a love letter to GBA fans rather than a derivative clone.

Beta Watchlist
- Boss encounters: Unlock demo bosses for deeper combat insights.
- Hitbox calibration: Fine-tune collision detection in platforming.
- Skill tree depth: Reveal full branching paths and advanced pet synergies.
- Accessibility: Expand keybind options and add colorblind modes.
- Lore expansion: Integrate more diaries, murals, and NPC side quests.
Conclusion
Tako no Himitsu: Ocean of Secrets’ Steam demo delivers a potent mix of GBA nostalgia and modern action-RPG sensibilities. Chunky sprites, dual prologues, octopus companions, and seaside lore coalesce into a demo that’s both familiar and fresh. While puzzles and platforming occasionally need finesse, and keyboard support requires polish, the core systems are robust and promising.
With a Q4 2025 launch on the horizon, CometTentacle Games appears set to refine these elements into a cohesive whole. For JRPG fans yearning for chunky pixels, oceanic mysteries, and strategic combat with a tentacled twist, clearing your schedule and diving into this demo is a must.
