this is my first creation i hope you like it i was inspired by popularmmos mini-arena to build this and its was attempted to make in 1.16.1 but then it corrupted so i had to restart after another 30 minutes of barrier placing i have recreated it for 1.12.2 but can be used in higher version but do copy the world if you are going to use in higher versions to avoid corruption.
NOTE: please tell me of any errors in the map i have not tested every version so please report any version incompatible.
