You would be able to recognize what requires AMP and what doesn't with more experience in mapping overall. Mostly you just need to create tons of relays instead of using target2, target3 & target4 keys for many things in the map.
Having your first map not become uber popular is not a reason to give up on making your own maps. There is a lot to learn before you can make maps that will be considered very good and even then you will still need to put a lot of time and effort into it.
Getting it to work without AMP would be great except it won't work as it's just not designed for conventional Trem gameplay.
I find most of the changes unnecessary. Especially having sub-matter reactor copied to repeater room

It's probably not possible to properly revive this map without AMP and "restore it's former glory". Without AMP you just have to cut out too much.
