September 5 Update — The Rush Steam update #538411

- More steam achievements added (a couple are still unobtainable, sorry) - 5th Stage Boss (Captain Kidney) was slightly reworked, and will no longer glitch out of bounds - A few bosses received total hit point nerfs - The "Extend" weapon's tentacle was increased in length - The final stage item layout was altered slightly - Some background graphics were altered to improve visual clarity during 5th boss fight, and to make them look better overall
