All those elements are usefull...
DIRT: new soil, does not burn.
MUD: created when DIRT is mixed with water, sticky, paints other elements, leaves WTRV when heated.
HRDD: Hardened dirt, created when MUD is heated, as resistant as GLAS and disform a bit like GOO.
TDRT: Thin dirt, created when DIRT is exposed to pressure, irritate any living organism and remove 1 life per hit. (Not related to stickmen, related to health)
MTRT: Meteorite, explode and spread fire while heating element touched to atleast 1,000C, leaves a trail of FIRE behind itself and goes mostly downward except when repeled. (Not a moving solid)
COMT: Comet, explodes and heat but leaves WATR on the element touched, leaves a WTRV trail and goes mostly downward mostly except when repeled. (Not a moving solid)
VPIP: Vaccumm pipe, it is obviously a pipe, have brown brick walls tmp2 to make brick brown, pipe inside is replaced by negative pressure to bring the elements at a specified direction chosen by the player.
Uses:
DIRT can be used for decorating as a better looking soil.
MUD can be used for trapping stickmen or painting things brown.
HRDD can be used for building a bunker not very resistant but not to easily breaking... maybe as a first layer.
VPIP can be used for sorting elements faster and easier than a PPIP or a PIPE.
MTRT can be used for bombing and making guns. and usefull for history saves.
COMT can be used for creating atmosphere of WTRV and making history saves while having fun seeing destruction caused by it.

So you say that none of them are atleast a bit different, I thought meteorites would be great since they fall instead of flying like mort and do a quite powerfull explosion... if my sentence is incorrect I will try to fix this. Thank you for the information on linking my save, I did not knew how to do it on the site. I can not fix this exactly like you want without making my element describtion messy.
