Good job figuring it out! It is designed the follow like the "intended line" of the game's "quests", but it is also the most readily leapfrogged I think? That's just based off my feelings about it and not hard numbers XD
Good job doing all of the game's quests! Sorry to tie up more of your day with it, but awesome job all the same. If this was still the 80s or something you could probably send in a card and get like, a high score reward type thingy like companies used to do!
