End City Takedown

This is a new map i have started, that will be like a 2D adventure, each level gets harder and you need to kill the enemy's to get loot and money to buy gear and improve your strategy. Your end goal is to get to the top of the end city and defeat the boss. Shulkers will be your main enemy but there will be more to add in to. I have found a way to get shulkers to drop the items i want them to. However, i would like assistance withe either the building itself or the command block factor. If you would like to volunteer to help, you will get credit as one of the maps makers and help develop the idea. Builders, Redstoners, Command Block Experts, And A few custom textures are needed.
