ADDING STAGE "REVERT" FEATURE • If you fail to clear a stage but have enough credits, you can use them to "Revert" the stage and try again. • The "Revert" cost is 200 credits at Stage 2 and increases by 40 credits for each subsequent stage. • However, if you continue a game that was in progress in a previous version, restore points will not be available, limiting the "Revert" feature and causing the game to reset. ADDING "UNDO" FEATURE • An "Undo" button has been added to the bottom left of the screen to recover from input errors. • The "Undo" feature cannot be used consecutively. OTHER FIXES • Fixed an issue where game information was displayed incorrectly on iPhone SE models. (Temporary measure: all info is accessible, but the UI is not finalized; it will be properly fixed when the layout design is overhauled) • Fixed an issue where volume and theme settings were not maintained after app restarts or recovery from sleep mode. • Fixed a visual bug where molecular structure animations were covered by bottom buttons. • Fixed an issue where phosphoric, phosphorous, and hypophosphorous acids were incorrectly set as strong acids. These compounds no longer trigger neutralization reactions. • Renamed alkylmagnesium halides to the more common term, "Grignard Reagent." • Corrected the Chinese terminology for Grignard reagent compounds. • Improved the readability of encyclopedia descriptions for sodium, magnesium, phosphorus, and sulfur compounds.

• Structural formulas are now displayed on the screen when creating a molecule or when a molecule reacts to earn points.  • Improved the resizing logic for structural formula vector images in the Molecule Info page to remove unnecessary whitespace.  • Added dynamic font scaling for the stat box in the Molecule Info page to ensure large numbers are displayed clearly.  • Updated Amine naming conventions to follow common nomenclature (e.g., Methylamine) instead of IUPAC standards (e.g., Methanamine).  • Modified the encyclopedia descriptions of some molecules for better readability.  • Introduced over 100 new molecules with a focus on alkaloids: Ammonium Hydroxide, Ornithine, Quinolizidine, Ecgonine, Ecgonidine, Nornicotine, Cathinone, Ricinine, Quinazoline, Coniine, Caprylic Acid, Castanospermine, Swainsonine, Hygrine, Indolizidine, Retronecine, Tropinone, Theobromine, Spermidine, Pyrrolizidine, Niacin, Mevalonic Acid, Pipecolic Acid, Histamine, Uric Acid, Piperidine, Pyrrolidine, Allantoin, Muscimol, Thiazole, Oxazole, Cholesterol, Solanidine, Cyclopamine, Mitragynine, Voacangine, Lobeline, Colchicine, Noscapine, Laudanosine, Yohimbine, Coronaridine, Glaucine, Ajmalicine, Heroin, Hydrastine, Serpentine, Ajmaline, Ibogaine, Papaverine, Protopine, Camptothecin, Ibogamine, Sinomenine, Cinchonine, Naloxone, Thebaine, Amurensine, Capsaicin, Oxycodone, Liriodenine, Solenopsin, Secologanin, Galantamine, Aporphine, Troparil, Febrifugine, Lycorine, Lysergic Acid, Sparteine, Matrine, Physostigmine, Tropacocaine, Acridine, Cuscohygrine, Ibogaminalog, Harmine, Bufotenin, Mescaline, Pilocarpine, Salsoline, Cytisine, Gentianine, Spermine, Lupinine, Saxitoxin, Actinidine, Xanthosine, Tryptamine, and more.
