Pulsekeep Arcanum

The siege is measured in eight beats. Your defense is written before the drum sounds. Pulsekeep Arcanum is an offline strategy puzzle about timing magical waves across a branching fortress. Place Ember, Torrent, and Howl pulses at tower sources, set their launch delays, rotate shared junction runes, and resolve the complete score. When different pulses collide on the same node and beat, they transmute into Steam Bulwarks, Frost Sentinels, Blazehounds, or the rare Crown Ward. Every handcrafted siege introduces a new castle graph, breach schedule, pulse inventory, and mastery condition. Scrub the beat trace, understand every collision, revise your plan, and defend each gate at the exact moment of impact. Explore ten siege scores, collect resonance shards, unlock cosmetic drum skins and ward tracery, and consult a fully illustrated Field Grimoire. High-contrast state marks, reduced motion, large touch targets, and clear written rules keep every plan readable.
