This is a lava rising map i made in my free time with only commands. It took a few hours to make, but even then, it is very fun. It hasn't been tested very thoroughly, but it has been tested at lest 5 times, which is enough for me! It is sadly one time use, but you can always copy the world! I have fixed the lag and it should be way smoother now.
