Just add fishing. add more kind of swords. MAKE IT A RPG. new kind of shields. New kind of arrows!
It is very simple, though. Stop making ****ty pixels(hats, mounts) and make fun things. I'd really like to see armors implemented(for gods sake, if you implement this, don't make "Different style pixel armors", or expensive armors).
Let us enchant our weapons. Give us some new attacks!.
But i guess i wont be adding more ideas cuz knowing this game, they'll make everything cost more than what i gain in a year of working.
