For features, I suggest putting a microscope view. Like pressing Z to use zoom, you should be able to press M to use microscope. When in microscope mode you could see 3x3 atoms and molecules. So if you break an atom by using a breaking tool (another thing to consider), or erase at least one piece, instanly the object you broke will explode into a huge nuclear bomb, making the most powerfull bomb ever.

For elements, first dirt, just like powder, but turns to mud with water, and is slightly heavier than dust. Mud is wet dirt, its really a liqiud but is thick almost like a powder.

I think there should be quicksand, what you create when you set the ctype of sand to mud. It will sink stkm,powders,and fighters if they stay in it for more than 5 seconds, there will be no escape.

If you look it up from correctly from the internet, diamond can actually melt and break, its not really indestructable, in case you didn't know, but then again you probaly did but wanted something indestructable that wasn't a wall.

Photons laser are pretty complicated, maybe it would help if you added laser as an element to make it extremly hot as soon as it comes on screen,instead of heating the photons up. It also dosent leave the line, so when you set it together, a single particle won't leave the line. Some people like cold photon lasers, so you should add cold laser too.

Nuclear waste. It would be green and glows and would poison stkm at normal tempature. Nuclear waste would, mutate stkm into superheros, with flying powers, laser vision, could not be changed with dropping elements on him or prop, and incredible health, and he would grow more and more with water, until he was two inhces tall on the screen at high tempertures, it also give him an awesome cape and plasma and fire resistance. At low temperatures it would mutate him to turn a nasty green color and would shoot out acid, same rule with superhero, he would also have two heads. Sadly, no super health,capes, or flying.These effects will also, work on fighters, but instead of superheros they will become supervillans, with cold laser, and half the health.

One more suggestion, seeds to grow trees( just wood and plant, shaped like a tree),flammable!

Please consider moving solids! Thanks for telling me that breaking an atom won't cause an explosion, I thought it did, I looked it, up and only some do, and it's an explosion of energy. and stkm don't drown in water. Wood and vine is boring it's never realistic enough, and I wanted to see something grow. They added Jetboots, so why wouldn't they add super powers. A lot of people want more than realistic stuff. Most superheros got thier powers, from radioactive things, think about spiderman and hulk. No one criticizes the zombie idea. I read the comments the other day, but, no, apparently it's a perfect idea. I edited this because of some of the comments.
