Congo Bongo (also known as “Tip Top” in some places) is an isometric platform game developed and released by Sega in 1983.
Playing it, you would be forgiven for thinking that the game was a Donkey Kong rip-off, although it’s not a patch on Donkey Kong in my opinion. However: Congo Bongo is not too bad overall. The isometric graphics are nice and characterful, and… well, that’s about it.
Congo Bongo is one of those games that is infuriatingly difficult, and lacks depth, but has a certain charm and quality that makes you keep coming back for more. To a point anyway.
