Doraemon: Meikyuu Daisakusen

Based on the Kids anime about a robot cat from the future, Doraemon is a sort of Bomber Man in reverse. Instead of planting bombs, you dig holes in the ground to trap enemies then fill them in to finish them off. The game has a couple of difficulty settings, the harder providing more moving enemies to avoid or trap. There is a selection of different levels that alternate for variety (there are 60 levels in total), and the occasional boss thrown in for good measure.
