Normally I'm against giving people answers to games like this. But I feel its such a perfect and touching game that everyone should be able to see the end. So for those who need help with 19 and 20. 19 All you do is stack up about 5 or 6 guys at the beginning by jumping three times and hitting space. 20 I passed by just mindlessly jumping off and hitting space until there were enough guys to jump more times. Just keep running jumping and when you fall hit space. Back to my opinion of the game, this game is the gold standard of all games. It's a deeply moving piece with every detail in perfect harmony to paint such a bleak picture of "Hermits" life with the most perfect use of rhetoric which paints this mans life even clearer.
