The plan is to create a adventure map, but without a main story line. Instead there will be:
- Small challenges,
- Puzzles
- Explorations
To unlock new rooms, places or secrets.

There is built a code room where you can enter codes you find around doing stuff. The code is similar to a 6 sequence pin with numbers from 0 - 9. Entering codes will also unlock new places.

The map includes a 3 digit counter with 3 digit display giving you 1 point every time you unlock something.
This map will require no mods, just vanilla MC, so there is a lot of redstone work behind the scenes. you can at any time view your score on the side of the cave wall.

I'll put it up for download when it's done.
I used Ovo's Rustic and Pure Edge as texture packs.

It's not done yet, so please give me some feedback :D
