This game didn't seduce me. It's an old concept with a slight variation -- too slight to be interesting. And the graphics make it feel like a bad 3D game from the 90's. Also, I found it a bit slow where it has no reason to be. Surely the code needs to be optimized.
Still, there is potential. I give 4/10.
It's pretty much impossible to really strategize, or even tell which blocks are going to explode, because the blast radius of the bombs seems pretty random. Also, music helps just about everything. Kinda so-so, but good potential. :)
