Good day,
* It would be nice to see a lesser durable version of a shield made from acorn shells.
* a sled, so we can harvest materials faster over long distances, or an upgrade to the size of the inventory slot.
* maybe, ride an ant.
* "RAIN" (KILLER RAIN!) - there will be a countdown before the rain or maybe just thunder, a few hours before the rain. It will be dangerous to go out in the rain, you need to craft an item for this. Some areas will be inaccessible during RAIN, you need to run for shelter. Raindrops will be dangerous!
(Thank you for reading my suggestion)
