Not a fan of this because its not original its been made before, its not that its sloppy or badly made but its been made before, but i think that this one was made a bit better than some of the other ones
It has a good concept but people could easily survive if they just hugged the wall. Try making either a bigger barrier in the middle or some way for all the flying pieces to go through the middle (maybe another mancannon if you didn't run out or a gravity lift).
ive actually decided to do it on foundry but just a version 2 with another wall higher and a roof, look for in the next few weeks. SORRY FOR THE DOUBLE POST
