So i was thinking and thinking..
The player mechanics could do with some additions.
1. All animals go to sleep in the night, it would be nice if we could make so players get tired and sleepy as night sets. Indicated by yawning, and if player doesn't go to sleep in the night, the character gets over exhausted and user begins losing control of the player from time to time, and some other debuffs like energy running down quicker and walking slower. If one doesn't sleep for 3 days in a row, they start losing health.
Allow players to sleep and regain rest at any time of day, count down 16 hours before player gets tired from waking moment.
2. When player walks up steep slopes, it feels a bit silly. It would be nice to disallow players going up higher than about 60 degree gradients, and make them slip down larger than 60 degree gradients.
When they slip down, they cannot be controled and take reduced fall damage when hitting bottom.
Add climbing tools like climbing boots/axes to climb steeper gradients but not vertical walls or overhangs.
