Simplerockets 2 is the one most players are going to remember (I think). The change wasn't really necessary
@AgniCosmos agree with you. JNO is my favourite game of all time, but I feel really bad that anyone barely knows about this game.
@TronicOrbital yes, I got it already from someone else's post, but thanks
the only problem was that I didn't take square pictures, everything else was fine.
@AttackTitan09 check your nozzle length and throatsize. the exit pressure might be too high compared to the atmospheric pressure. Check the infos just as @Idiot99 said.
