A one-thumb arcade game with a sharp core loop

GLACIER is a one-thumb arcade game set in a frozen abyss. You are a cryo core — tap to emit a hoarfrost pulse that shatters incoming ice splinters. Master the FROST system: pulsing builds frost for a wider blast radius, but overdo it and you CRYSTALLIZE — locked out until you thaw. Destroy enemies close to your core to collect ice shards (3 = free pulse). Chain combos for score multipliers and survive the BLIZZARD SURGE event. 4 enemy types, escalating waves, local high-score persistence. Cyan/teal neon frost aesthetic on deep indigo space.
