The Lightwell is a tower defense that never ends. Build out from the Keystone on the Well, a board of light that grows as you push further. Waves never stop climbing and there is no game over: a bad wave pushes you back a little, then you build and try again. Calibrations raise every tower of a type at once, so your first defense stays useful as the board expands.
Every tower type does something different, eleven natures of shades join the waves as you climb, and new zones bring build rules of their own. Pulses are short runs on a fresh board, and each week there is a weekly Pulse with the same board for everyone.

Weekly ranking
Everyone plays the same weekly Pulse board. Every run on the ranking was replayed by this server, which computes the wave itself. See this week's ranking.
