It was a game where you placed bombs in a maze to, I think, open new paths and/or kill enemies, but this was a clone of the original and the game sprites looked like Doom characters... Bomber something? Boom?

Really old games, I'd say 90s...

Found it!

Damn, seems it won't run on Intel/OS X. I wanted to play it but not enough to bother with an emulator.

Looks like a ripoff of Bomber Man. If you were going to emulate, you might be better off exploring the Bomber Man series. In particular, some of the Super Nintendo releases were fantastic, particularly Bomberman 5 (which I think was Japan only).

That looks... boring.
