Ok, where to start... Not only does it take up the whole screen, look ugly, take forever to explode, but it isn't even a bomb. It is made of rings of element explosives (like c-4 and nitro) and it can't even break titanium. If this is your first bomb, i could understand. but otherwise, you really need to put more effort into your published creations.
you asked for comment so.. I think this is just a bunch of rings of everything in the explosives list. Not the best but keep trying!
