add more liquids and better rocket physics (basicly just rockets working with liquid fuel but not actual rocket physics like moving it because that would break the game.) also, add things like liquid hydrogen (more flammable and explosive variant of hygn, btw, it freezes at -253.) kerosene (more explosive and flammable fuel that burns half as long as 1 bcol pixel.) and also nitrogen because we already have ln2 (basicly just a different version of gas that creates a little bit more pressure than it and isnt flammable.) also add ethanol (more flammable than oil, less explosive and flammable than kerosene.
