Fun game
Rather addictive, easy to pick up. However would prefer if we could earn 1 energy per few minutes instead of waiting 4 hours to get only a handful of energy that can be used up in about 3 rounds. Also the 'hint' is can be a waste as sometimes it'll reinforce what you already did instead of fixing what you did wrong/showing you the 'way' of another dot (that you haven't done yet).
