Make it Juicy: Easy Methods to Make Your Game More Engaging is a presentation I made that lists various techniques I use to make my games more fun to play. It is largely based off of the Juice it or Lose it presentation by Martin Jonasson and Petri Purho (on Youtube at http://youtu.be/Fy0aCDmgnxg). I hope this educational demonstration helps other indie game developers improve their games as well.
