My suggestion is to have all of the stuff in your hotbar not in your inventory. Make it so that your hot bar is storage. Also I suggest that you make extra spots to put "equipment" on top of your armor not in place of your armor. I also suggest that you make a quiver that can store your arrows. Also I suggest adding grasshoppers. Also you could make it so occasionally a regular sized person walks through the yard. Or have it rain and if you get hit you take damage. Another idea would be to add a queen ant in the Western ant Hill. You could also add bosses. Also I have had a lot of issues with creatures glitching into rocks and trees (Especially ants). Also another suggestion I have is to allow the player to have multiple saved world's.
P.S. I'm on console
Also soldier ants do way too much damage.
Thanks for reading
