 * Maybe configure lights in separate json file, to allow reuse of consistent models in multiple levels?
 * Allow going down to zero seeds by buying lights if a turnip is planted
 * Maybe make the mould weaker at the start
-* Display average power usage in light tooltip
 * Maybe also display information next to existing lights -- tooltip?
 * Generally balance the levels better and add more levels
 * Graphical level selection with screenshots

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