Resonance

A tower defense where damage is a matter of pitch — your beams only bite when their tune matches an enemy's color, and some foes only fall to a blended note.

How to play

Defend the Core at the end of a winding lane. Place emitters beside the path and tune each one to the color of the enemies passing by — a matched frequency melts them, a mismatch does nothing. Overlap two emitters and their beams mix into a new color, the only way to crack enemies that resist any single pure tone. Survive ten waves to win.

• The Core has limited health; every enemy that reaches it costs you one, and at zero it's game over.
• Tune emitters to match enemy colors — the closer the match, the more damage.
• Overlap emitters to MIX a new frequency and defeat Chord enemies that need a blended beam.
• Earn energy from kills and cleared waves; spend it on more emitters and upgrades.

Controls

• Desktop: click to place an emitter, press 1-4 to pick a type, and tune with the color bar, the mouse wheel or the [ and ] keys; click a tower to re-tune it, press S to sell, and Space to start the next wave.
• Phone & tablet: built around mouse and keyboard input — a desktop or laptop is recommended.

Tips & strategy

• Watch the active colors rotate each wave and re-tune your existing emitters instead of only building new ones.
• Place a Mixer where two beams overlap so their blended color can break Chord enemies.
• Drifters slowly slide their frequency — a wide, forgiving Resonator covers them better than a sharp single beam.
• Save energy for Sharper, Range and Power upgrades; one well-tuned cluster outperforms a sprawl of mismatched towers.
