+* Light removing tool

+* Five levels
+* Bug: have to click lights multiple times to turn them back on after the power has died
+* Bug: Crash when removing a rotating light
+* Turnip / light spacing bug: a light can be placed right below a turnip, but must be much further away if above the turnip. This happens whether the turnip or the light is placed first. I assume it has to do with how the turnip image is positioned relative to its body.

+* Different prices for different lights
+* Calculate both from # of colours, speed, beam width, etc.?
