Brotherwise Games is the company responsible for the design and release of Boss Monster. It is an indie company created by two brothers, Johnny and Chris O'Neal.
Boss Monster is their first and currently their only work; though they have stated that they plan to release a 'non-Boss Monster' game sometime in 2014.
On the Boss Monster Kickstarter when addressing backers Chris O'Neal called himself 'Brother One' and Johnny O'Neal called himself 'Brother Two'. This was based on the fact that Chris is the older brother.
