Bango

You play as a certain creature named Bango, whose task is to exterminate bees (!) In a block maze for the sake of survival (this is an important point). In fact, Bango looks like a strangely shaped green creature with legs and big eyes, bees like the same creatures, but yellow. Managing the movement of the hero is very strange and unusual: O, L, K and ":", and it can not be changed.

It appears to be a hacked version of Pango. Likely with just the title changed and resold by Cosmi.
