MM345Sullen

MM345Sullen is a vertical survival shooting mobile game that combines flexible movement with continuous firing. Players control an energy unit by touching the screen, which automatically aims and fires, consuming energy to launch projectiles and repel enemies surging from all directions. Battles progress in waves with various enemy types, and every few waves feature a powerful boss. On the field, regular, magic, gold, and lucky four-leaf clovers spawn, providing points, energy recovery, coins, or random buffs; players can also pick up health, shields, magnets, speed boosts, triple shots, and damage-enhancing items to temporarily turn the tide. Coins earned from defeating enemies can be used in the shop to upgrade health, energy, damage, and movement speed, or to equip starting shields and magnets. The controls are simple, yet require balancing positioning, resource management, and wave rhythm—easy to pick up, yet strategically rich.
