It costs 2 energy to collect 1 emotion, you need 2 of the same (negative) emotion to create 5 energy, meaning you only get one surplus, this is the ONLY way to generate energy, everything else COSTS energy. This is an absolutely HORRIBLE economy. Also, LEVELING UP MAKES YOU LOSE IMMEDIATELY, as the cost of 'collect emotion' RISES to 4 per use (WITH ZERO BENEFIT!), meaning you now have to spend EIGHT energy to get FIVE back. WHY?!
