oblk or oobleck, liquid, gets harder the more something tries to move it
create balistic and kinetic mechanics, would be cool shooting projectiles made from various materials and seeing them penetrate other materials :DD
ye realistic antimatter would be better
BLCH (bleach) acts like soap, but doesnt make bubbles and has a larger deco removal range, soap removes 2 pixels of deco but bleach would remove 5.
I would love to see some kind of electromagnetic field so you could create makeshift wifi or transformers.
if it's too many, just make ORGM(organism), it's a solid that sucks oxygen and drinks water, if it doesn't receive water nor oxygen, it'll turn into DOGM(dead organism), DOGM also is a solid, but it can't drink water and can't suck up oxygen, ORGM's color is brown, DOGM's color is pale green
then, why not add FOSL(fossil)? along with FLSH(flesh), BLOD(blood) and skin? fossil is just concrete but extremely white, flesh is just SPNG that slowly turns pale green when it's not touching (or storing) blood, blood is just distilled water that sucks up oxygen around it and disappears if there is no oxygen, skin that is just wood but a different colour. hope you can make it :)
Make graphite a thing, it should moderate neutrons. And also, make the existing radioactive elements more realistic
and because real antimatter explodes on contact with any matter
Because tpt Antimatter is horrible
