The same concept has been done loads and this didn't really add much to it. Other games in this genre are usually colorful and have multiple types of bombs. This is dull, dark, and only has one type of bomb. Adding colors would definitely improve it.
I don't like the choice of in-game music. It feels really unsuitable for this type of game. It's just a few drum loops thrown together. It's boring. I think trance music, or something similar, would be a lot more suitable for this type of game.
One thing I liked about this that I haven't seen in other game like this is the fast forward button. Nobody wants to wait to watch the bombs slowly drift towards the explosion region. It definitely helps make the game feel less repetitive.
I found one glitch. If you go into the high score menu once you leave the menu it will unmute the in-game music.
