faster mining (or woodcutting) faster walking faster building (if there is build times) faster healing strength up if you have armor in the game then armor up
i am a solo game dev who is currently making a 2d survival game where you have to build shelter before night and monsters come out then (totally an original idea) you can have npcs that do stuff like get materiels and food. sadly, i do not know how to make the users progress save when they log off, so that kinda sucks, but it is gonna be for mobile and subscribe to me for updates on how its going (new pixel art, big gameplay updates ect.) and probably some videos too. i will also have a big celebration when its done!
