ok, i have a neutron bomb
To improve your work i would reccomend looking at other people's saves to find out better bomb designs and look at better elements to use for them, you'll notice that a lot of them might use neutons/protons and high life deuterium to generate better explosions.
Not to be annoying or offend you, but the comments are somewhat right, sure, the explosion looks cool, but it's not symmetrical. It's not very pleasing to the eye, mainly due to the fact that you put random things from the explosives category randomly in the bomb, most things in the explosives category don't do much damage either, so, especially for it's size, the bomb is inneficient.
