My favorite part was figuring out that qt means "quintillion" and o means "octillion." Both of which were strictly nonsensical words prior to playing this game. :)
do the last level enough times to kind of memorize the pattern of mobs. You can get it all with the 4 meteor cannons, and still have your bomb left for the boss. Extra bombs picked up along the way should be used when there are mobs coming/going in all 3 directions.
the total money required to feed the dragon 200 times (depends on level, but you shouldn't go for the sword til lvl 9000 or 9001 anyway) is around 4 billion. 200 mil wouldn't do much for you. sorry.
@ettyone: v1.348: from the updates, "Well, I decided to end some big load of whining by increasing the chance of Legendary items from treasure chests – an increase of ~0.05% chance for each digit in the number found (1 = 1 digit, 10 = 2 digits, 100 = 3…), on top of the 5%." so, it starts at 5% and goes up slightly as you find more treasure chests. Hope you get them soon! :)
