This is an interesting concept, controlling a power plant with just two buttons, and trying to balance temperature and meet energy quotas. It's quite unique, and I would never have thought staring at three lamps would be anywhere fun before this game. The random events are also quite a nice touch, and it really makes the game unpredictable at times. Nicely done!
For some criticism, I'd say the game lacks a clear state. Currently, even if you fail a day you can still progress through the game. I think it's better to do a game over and force the players to restart the game. The game also doesn't scale difficulty with the levels, and it feels like every day is the same. It would be nice if there were more things to juggle besides the two buttons, such that it's more chaotic and interesting to play.
Anyway, this is quite an interesting entry indeed. Nice work!
