Ice-shard towers melt and shrink after firing; keep them cold with limited snowfall charges or they vanish. Blizzard events cut all ranges; clear spells restore line of sight. Signature: budget melt vs fire-rate in real time.
Pale blue and white palette, crystalline facets, wind streaks, low sun glints on snow.
Click, Enter or Space to start. Place and upgrade towers with the mouse and number keys, or by tapping on touch, to stop each enemy wave before it reaches your goal. The HUD tracks lives, cash and wave.
