How to play

Everything comes home.

  2. Payloads become coins only when they reach the smiling core.
  3. Mix rapid, splash and chain attack towers. Upgrade their power and target radius separately.
  4. Place colored aura tiles near the facilities you want to strengthen.
  5. When Smile Burst is charged, click the core to blast nearby letters backward.
  6. When the letters become too strong, Prestige and spend sparks on permanent skills. Repeat until Z falls.
