Overbearing Burgers by Sebastien Mihai is a Sega Dreamcast homebrew game featuring a hungry brown bear. The bear must jump at the right time to not only not hit the rocks on the ground, but also to not miss any of the hamburgers. Overbearing Burgers is very easy to play; the only button used is A, which will make the bear jump.
