Redstoneseption is an awesome puzzle map with lots of rooms filled with redstone. The aim of each room is to guide a piece of glowing redstone to either a door or a diamond block. However some rooms have PORTALS which travels the signal to the other portal of that colour. It is a very fun map but you do begin to rage. At the end of the map there's also a nice surprise that you will enjoy :).
Make your way through a series of rooms, solving super simple redstone puzzles by placing 2-5 redstone dust in the right places. There's a unique concept here, of redstone signals flowing through portals, but it's executed a bit blandly. The last puzzle is something I've never seen before. Somehow, this map has a positive FEELING to it - you can really tell the map maker put effort into it, and we actually enjoyed the challenge.
Assuming you're new to making puzzle maps, this was a really good effort. The only downfall for me was that when I opened it up initially I was in the room for the last puzzle, and in creative mode. I had to locate the entrance on my own (which I was only able to do because of rsmalec's video), and I had to use gamemode commands to put myself into survival, as well my inventory had a bunch of materials in it that I had to get rid of before beginning.
