・Apology gift: claim 30 bonus gacha draws via the gift icon on the Gacha screen

・Bug fixes

Description
Collect all 118 elements through daily gacha draws and build your own periodic table.
Each element has a rarity based on its atomic number — lighter elements appear more often, while heavy rare elements are harder to find. Upgrade your collection from Normal to Diamond rank as duplicates accumulate.
USE YOUR ELEMENTS TO SYNTHESIZE COMPOUNDS
Combine collected elements to create 46 compounds, from simple molecules like H₂O and CO₂ to rare noble gas compounds like XeF₂.
FEATURES
• Daily element gacha with atomic-number-based probability
• 118 elements with 5 rank tiers (Normal → Bronze → Silver → Gold → Diamond)
• 46 compounds to synthesize
• Interactive periodic table with pinch-to-zoom
• Daily & weekly missions with bonus gacha rewards
• Long-term goals across 10 categories
• Login streak tracking with calendar view
• Available in Japanese and English
A fun way to learn chemistry while enjoying a casual daily game. Perfect for students, educators, and science enthusiasts.
