MInecraft but every three seconds a chest with random loot spawns (you don't need to reload)

This datapack took me 7 hours ( ':

Please if you make a video with my datapack, please put the link somewhere so that other people can play it (:

Tips for a gameplay:
1. If you stand on a chest it will replace the it with a empty chest, thats the only block that won't replace
2. The timer is shown above your inventory
3. The chest will spawn one block under you so if you stay in a dirt path the chest will spawn under the dirt

Thats all
HAVE FUN!ツ
