Amazing Bumpman was released by Telegames in 1986 for the Colecovision, quite late in the console's production run.
It is an education game, math in particular. The player must bump numbers into place to solve equations. Bumping is even how to center and move the screen in place, which is annoying to say the least. The controls are also pretty terrible, as well as the game's fatal flaw.
Due to the late release in its console's lifespan , copies of Amazing Bumpman go for $255 loose and $420 complete.
