Well you clearly haven't tested this map before.
I am literally unable to play this map due to the stupid thing that you spawn next to, constantly placing redstone blocks.
So I am just going to have to judge from the screenshots. All of the things you said that are in the map, and that I saw in the screenshots have all been turned into levels before...
Originality is key for jigsaw!
And Zainos has previously stated that due to the huge success of Jigsaw, he may create another adventure map based gamemode, but it would have to be good and unique to compete with Jigsaw.
Yes, the obvious theme to the majority of the pre-existing jigsaw levels is a sort of dungeon, but we do have unique levels that aren't like that (27 for example) But this map would have to be split up into multiple levels, and you said that you get items from one part of the map to use in another part, this really wouldn't work on Happy Hunger Games.
So I am sorry to say, but this map has been declined.
