YMMV / Alchemy Stars

• Awesome Music:
  • With Asami Tachibana in charge of the game's music, it's no surprise that there are a lot of amazing tunes in the game.
    • Under the White Night features a swath of violins accompanied by a female vocalist and a piano, all of which evoke the elegance, austerity, and rigid faith that Lumopolis inspires.
    • Bubble & Soda is a bouncy, jazzy tune to unwind to.
  • White Midnight, which was written by Reol for the game's 2021 summer event, is a lively, heart-pounding piece, combining the uplifting fantasy elements of the game with Reol's signature EDM style.
• Friendly Fandoms / Fandom Rivalry: With Arknights, since both games are gachas with chibi sprites/models of characters appearing on a grid-based battleground (though the genres are quite different). Some fans like both games, and others insist that one is better than the other, but regardless, the games' fandoms are intertwined quite a bit.
• Harsher in Hindsight: Regal's story becomes this when it is revealed that his voice actor, Tatsuhisa Suzuki, cheated on his wife. Tourdog ended up replacing Suzuki with Shintarō Asanuma.
• Launcher of a Thousand Ships: The Navigator is frequently shipped with a variety of characters, especially with Vice and Carleen.
• Role-Ending Misdemeanor: Tatsuhisa Suzuki cheating on his wife caused him to be replaced with Shintaro Asanuma as Regal's voice actor.
• That One Boss:
  • Stage 10-14's boss battle with White Schummer is extremely frustrating. The stage features four daemons that are attributed to each element, and will activate one by one. Once a daemon is activated, the Aurorians matching its element will be locked out of using their active skills. When all four daemons are activated, the boss will cast a full-screen One-Hit Kill that results in a game over, regardless of your team's health. The only way to deactivate the daemons is to activate Aurora Time, something that players may be hard-pressed to do without a reliable converter and/or good tile RNG. The upside is that Schummer herself deals relatively low damage outside of the One-Hit Kill.
  • Chapters 11 and 12 of the story introduced Claudia (and Asher), who was widely bemoaned by the playerbase for her ability to avoid most attacks when on top of her floating platforms/Asher, as well as how she will teleport to another platform/Asher when the one she is on gets destroyed, making her nigh-untargetable without a proper sniper. It doesn't help that Asher is able to stun the player if they are anywhere near it. A tip for dealing with Claudia is that she only teleports to platforms within two clusters of her, something that the game fails to mention.
• They Wasted a Perfectly Good Character: The Miss Kobayashi's Dragon Maid collaboration characters are often viewed as a waste of potential by the players, as the collaboration mainly featured a simplistic lottery event and a login story, with no interactions between the two franchises' characters and no interludes for the collaboration units.
