explore new biomes, structures, items, and customization. This was made for me and my friends, do not expect something good, just pure fun doing parkour and exploring
you can explore new structures in the overworld, like towers, some houses, and exploring will gave you some loot so you feel more rewarded, there is new dimensions like midnight that adds new monsters a dimension kinda scary, new biomes in the nether too, with some vibe to it.
besides that, there is some QoL mods to help you, there is mods to organize your inventory, mods to upgrade chests and furnace for better performance and efficiency, backpacks so you can have more loot and explore even more, effortless building, so you can build very fast and in a fun various way, new plants to your farms, new animations for player (that you can change however you'd like), new effects and sounds for more immersion, there is voice chat too, so you can talk to your friends in game, you can do parkour that makes you jump higher, can make wall ride, its a very fun mod to bring more variation to your gameplay. It has create, that basically makes that you can make easier farms and new farms to bring more facility to your life, and it is very fun to mess with the machines and see what your imagination can create.
