A better name
Also, please stop putting FEN... I don't quite get whom it is for. If you expect others to copy it and then load it in the Edit Position to do some analysis (+ setting up all the gamerules manually), just provide a link to a simple test-game.
Any suggestions for this position?

Well The reason why I put the FEN there instead of link is because there are no games and I want some people to help me test it. Also, there are no major issues? Only the name?

Also for the name what about Barricades of the Field?

bots are usually dumb enough to mess up the whole game, but I'll go for it then
You can literally just start a game with 4 bots, abort, and post link
As for the position, the idea is unique and pretty cool, but idk about balance (looking at the position for more than 5 seconds makes head explode bc new piece symbols are too ugly), you will just have to play some test games.
i managed to get a few and I find it pretty interesting as long as players know to play it or at least listen to arrows. I had one person tell me it was boring, but no one else gave me such reaction. The bad part is that bad teammates can just heabge their bishops and lose them.
