This looks amazing! I've played it a few times with my brother.
The AI is a bit strange though, on 1 they barely move, but on 2 they are experts.
I would definitely recommend the explosion sound from Super Bomberman 5. I agree that it is one of the most satisfying explosion sounds in the series.

I was also wondering if you could add the skull bombs/super bombs from Generations and Ultra? That would be awesome.

I'm glad you're showing recognition to past bomberman games, I was pleasantly surprised to hear a battle theme from Bomberman Online.

Keep up the amazing work!
