Hi y'all! Here's my "route" for this game's any% run. By route, I mean what you should be upgrading after each level.

After level 1: - 2nd shooter upgrade - 1st shield upgrade - 1st death ray upgrade After level 2: - 1st health upgrade After level 3: - fancy hat (doubles money) - 1st shockwave upgrade (if you can afford it, you probably will be able to if you're collecting as much money as you can) After level 4: - 4th shooter upgrade - 2nd death ray upgrade - 2nd health upgrade After Grinning Colossus: - 3rd health upgrade - 2nd shield upgrade - 3rd death ray upgrade After level 6: - 6th shooter upgrade if you can afford it. You should be able to if you've been collecting as much money as possible during the levels. - If you can't afford it, you're probably better off resetting or not upgrading anything. After level 7: - Max out health - 4th shield upgrade After level 8: - 4th death ray upgrade at least - Nothing if you're 78000 money away from 300000 After Fishhead: - Prioritize the 7th shooter upgrade. - If you can't afford it right after, don't buy anything until you can afford it. - Once you have it, continue upgrading shield, death ray and shockwave until they're maxed out - Your final task is getting the "troll face" upgrade (-_- i know) and once you have that, you can completely ignore money and just beat the rest of the game!
