ADD this elements:
Liquid:
BASE- the opposite of acid
solid:
Carbon-CABN-when mixed with O2 makes CO2, organic (IDK .. add more info)
make a option to make a solid movable(checkable) when your gonna put a solid
PIG - which can be cut into pieces or meat , may be eaten by Stickman
BALL - a ball(movable solid)
make sponge movable or stretchable so when squeezed will releas water (if it had absorbed water)
Dry Ice-DCIE- pressurized CO2 and cooled at very cold temp., Very cold
gas:
make O2 not flammable make it oxide something
Helium or HELM - a gas
Propane-PRPN-Flammable, adding excess oxygen will form CO2 and H2O
Carbon DiOxide-CO2- Produces Heat and Pressure when trapped, if pressurized makes carbonated water when mixed with water, turns DCIE when pressurized and cooled in very cold temp.
NEON - when added by noble gases(helium or what ever) will change color, when electrified makes the "neon" effect if you know what I mean

00--ADD MORE--00 COMMENT FOR NEW ELEMENTS

oh yeah 100 000 C for temp
Idont want mods
neon is cool
pig IDK its just meat
CO2 is useful in some ways

Ok no movable solids but add gases gases are so few
BASE can kill STKM
reacts with oth.. whatever
