I agree with Console Compulsive. My first thought was Pengo. Nice looking game.
Played this on the Intellivision emulator Nostalgia.
I do not want to ruin your review but will say it plays like a free roaming Pac Man.
Too bad about the glitch but at least they found it before shipping.
I did not play much of the rom. I wonder if the glitch is present. At times it seemed slow but that could have been the computer or emulator.
