"KUDOS" is the company that the developer is working for. The developer is known as "BMB", But I have a theory related to his identity, his actual pseudonym (as they credited themselves secretly on a hidden sublevel in level 9 in Mario 3) is CARI TZAR.

If we look this name up, we get the following results:

• CARI TZAR's account on a Russian forum dedicated to ROM hacking
• CARI TZAR's website
• An incomplete Sega Genesis homebrew game (made with the same SDK BMB's games are made on, SGDK) based on a PS1 game called The Neverhood, that they were working on back in 2009

The incomplete homebrew game has similar physics to what you would find in a BMB game (might be a coincidence)
This might have been BMB's online identity before they got hired by KUDOS to work on games (Mario 3 is most likely the first game they worked on for KUDOS)
