Theyre unreleased and theyre kind of garbage as theyre mcreator mods :/. I dont really have the patience to code them from scratch. One adds terrain blocks eg. coral, colored sand, lunar soil, martian soil and rock etc. The latter blocks are textured based on NASA photos of the actual dirt and rock of the moon and mars. I added the moon and mars as places you could fly to using the elytra. Venus and a few other places were added and are based on old scifi depictions. The elytra flight mechanic was based on an old DnD campaign I was part of where planets and moons could be visited via hot air balloons.

The other mod adds custom potion effects. eg. a potion that burns the player when theyre in the sun, one that deals damage if theyre in water, "cursed" potions that do things like close containers as if a cat was sitting on them, technical potions that do stuff behind the scenes eg. execute commands etc. I think its up to 40 or so by now.

Id like to eventually recode them from scratch but there are hundreds of more pressing issues with the pack.
