DD3offsetEdge is a vertical scrolling survival shooter. Control a frost knight on a hovering board, battling endless waves of descending enemies in a blizzard. Drag to steer; weapons auto-fire at the nearest threat. Waves escalate continuously — enemies spawn faster, move quicker, and grow tougher. Defeated enemies drop crystals and power-up pickups (health, shield, rapid-fire, double-shot, magnet). Three active skills — Blizzard (AoE slow + damage), Nova (knockback + damage), Magnet (wide pickup suction) — are essential for survival. Crystals accumulate and can be spent in the Arsenal to unlock permanent upgrades (Polar Shield, Rescue Heart, Magnet Drive, Blast Core), making every run stronger.
