Alchemy Stars

Alchemy Stars arrived in mid-2021 as a mobile game that felt like it was trying to do something nobody else had attempted. Developed by Tourdog Studio and published by Level Infinite, it combined tactical RPG combat with a tile-connecting puzzle system that asked players to trace paths of matching elemental colors across a grid. The result was a game that looked stunning, sounded even better, and played unlike anything else in the gacha space. It also struggled with some of the same problems that plague the genre, and a few that were entirely its own.

Community opinion across the game’s three-and-a-half-year lifespan settled into a clear pattern. Players who stuck around loved the presentation and the core combat hook. Those who bounced off it tended to do so quickly, finding the tile-matching either thrilling or cold within the first few days. The game maintained strong store ratings on both iOS and Android throughout its run, and its dedicated player base mourned loudly when the shutdown announcement came in late 2024.

The Art, the Music, and the Tiles

Nearly every player who talks about Alchemy Stars starts with how it looks. Character designs drawn by over 150 illustrators gave the roster a visual variety that most gacha games can only dream about, and Live2D animations brought those characters to life with subtle movements and expressive detail. Higher-rarity characters received especially polished animations, which made pulling them feel rewarding beyond just their combat utility. The overall art direction blended fantasy and sci-fi elements into a cohesive aesthetic that carried through menus, cutscenes, and the world of Astra itself.

Asami Tachibana’s soundtrack earned similar praise. Her compositions ranged from atmospheric ambient pieces to aggressive, jazz-fusion-inflected battle tracks that matched the tone shifts of the story. Music in gacha games often fades into background noise after a few weeks. Alchemy Stars had players actively seeking out its soundtrack releases.

Then there’s the combat system, which remains the game’s most distinctive contribution to mobile gaming. Instead of a standard turn-based system, players traced paths along connected tiles of matching elemental colors. Longer paths meant stronger attacks, and chaining 15 or more tiles triggered Aurora Time, granting an extra turn with refreshed abilities. Building teams around elemental synergies and reading the board for optimal paths created a puzzle-strategy hybrid that rewarded careful planning. For players who clicked with this system, nothing else in the genre offered anything comparable.

On the monetization side, the free-to-play model held up well. A 2% base rate for the highest-rarity characters, a guaranteed five-star-or-higher pull within 21 attempts on the beginner banner, and a pity system kicking in after 50 pulls made the gacha feel fair by genre standards. Lumamber, the premium currency, flowed generously through daily quests, story rewards, and events. Players could clear all content without spending money, and Tourdog Studio built a reputation for responding to community feedback with meaningful quality-of-life improvements.

Where Alchemy Stars Lost Its Shine

Auto-battle was, by wide consensus, terrible. The AI controlling automatic replays of cleared stages made baffling decisions: landing combos far from enemies so area attacks whiffed, ignoring obvious tile connections, and wasting abilities on unhelpful color changes. It consistently took far more turns to clear stages than even a mediocre human player would need. For a game that expected players to farm materials regularly, this was more than an inconvenience. You couldn’t close out of a battle during auto-play or override the AI mid-run, which meant watching it stumble through stages you’d already mastered.

Repetition became the larger problem over time. The tile-connecting combat that felt fresh in the first few weeks could start to feel like a routine after months. Players noted that the story, set in the world of Astra where Aurorians fight invading Eclipsites, followed a predictable structure: arrive somewhere new, discover an Eclipsite threat, fight the Eclipsites. Dialogue sequences between characters could stretch on with small talk that added little to the narrative, turning what was initially praised as an engaging story into something players started skipping.

Resource grinding hit hard for players building deep rosters. Upgrading characters involved multiple systems (leveling, ascending, breakthroughs, equipment) that each demanded different materials. Strengthening even a single character felt like a project, and with a roster that grew to over 200 Aurorians, the sheer volume of farming required could be overwhelming. The broken auto-battle made this worse, since efficient grinding meant doing it manually.

Storage requirements also frustrated players. The game’s download size ballooned over time, with some users reporting it consumed upward of 17 to 24 gigabytes. For a mobile game competing for space with photos, other apps, and operating system updates, that footprint pushed some players away entirely.

A Game That Couldn’t Outlast Its Own Ambition

Alchemy Stars shut down on January 24, 2025, after roughly three and a half years of service. A limited offline edition preserved the story and basic features for players who wanted to revisit the game on their existing installations. The closure reflected a reality that the community had been sensing for a while: update frequency had slowed after 2023, and power creep in newer character releases had started undermining the viability of older units. Even the generous free-to-play foundation that attracted players early on wasn’t enough to sustain the game when the content pipeline thinned out.

Should You Play Alchemy Stars?

The offline edition means the core experience still exists for players curious enough to seek it out, though without ongoing events, multiplayer features, or new content. If you’re drawn to tactical puzzle combat with a strong visual and musical identity, there’s still something worth exploring here. Players who need a living game with regular updates and an active community will find that Alchemy Stars has already told its story. The gacha system, once one of its biggest draws, is frozen in its final state.

The Verdict on Alchemy Stars

Alchemy Stars was a game that nailed presentation and carved out a combat identity that no other mobile title has replicated. Its art, music, and tile-connecting battle system set a high bar for what a gacha game could look and feel like. Those strengths were real, and the player community that formed around them was passionate and loyal. But repetitive gameplay loops, a notoriously bad auto-battle AI, and a resource grind that punished broad roster building wore down that goodwill over time. It was a game that aimed higher than most of its competitors and fell short in the places where daily play actually happens.
