Hello
So I made a secret dirt house base with 3 different locks.
1. Press button to open
2. Drop an item in a tree to open
3. Drop an item in the water to open
The schematic is for version number 1
And the World has all the versions and a surprise :)
I really advise you to try out the world, it's almost like a adventure map couse
it has 2 secrets that I spend more time building then the dirt houses.

Try finding the secrets, It's worth recording :).
