The Avelon submitted a new mod: Vanilla Jump ++ - Jump, magic, jump magic jump. Read more about this mod...
Pulse (multi) Jump not working in Starbound v1.3.3 SP, also no fall damage isn't working while holding jump key without pulse jumping.
Very sorry about the late reply! I'll be reinstalling SB and testing this soon. The no fall damage works only with the basic vanilla pulse jump - the one you get for helping the tech scientist test his techs.
I'm reinstalling very soon, and will be updating this to include a free flight version of rocket boots. After that I'll probably create a sister mod that applies similar changes to common tech mods.
