Chou Bakudan Otoko Densetsu

A good looking Bomberman homebrew. You play a man who is trapped inside a maze. Place your time bombs wisely to defeat the balloon monsters. If the balloon monsters get caught up in an exploding time bomb, they will pop and disappear. Defeat all the monsters on the screen to proceed to the next stage. You can break down weaker walls with your time bombs. These walls can hide treasures and exit doors. Pick up treasure to receive bonus points. Go through an exit to proceed to the next stage. If you accidentally blow up a treasure or exit, four monsters will come out and attack (only once per stage). Move up, down, left and right with the cursor keys and press Space to set a bomb.”

Bombs contain some traits unique to this title, such as "half-blasts" - bombs can be placed between spaces on the grid and blast half the soft wall away, although the way is still impassable unless it takes a full blast.
