Greasy Fork is available in English.
How to use: You should see a menu bar on the right side of the screen, hover over it and the menu will slide out! When out click on the buttons shown! This should upgrade your tank automatically! If you don't know what the upgrades do, press [T] twice/once.
I love this script it's the one i started with and it works really well! It doesn't feel like cheating (and isn't) and just lets you play the game without having to memorize the builds for everything! It has no flaws (maybe except the join honey promo (?))
ïdea: maybe make the upgrade auto too? that'll be cool
