Next version will include a little rework of healing items.
Your character will have new "health" stat. This stat will be affected by your vitality and wellness.
Each week, you will be able to heal the amount of HP equal to your health stat by using healing items. Using healing items beyond that will have no effect. This number resets weekly.
This will basicaly limit the amount you can heal with items every week. Bandage sprites from using first aid kits will be changed to work with this system.
