This mod adds some new (unbreakable) blocks. You can use this mod to make your house or building (almost) impossible to pass (for people with no chorus fruit lol).

It'll add the following blocks:

Password Block

First provide a password, and nobody will be able to pass without the password ever again.

Use this to create Key Cards, you need to put a keycard into the slot, and then you can change the data of it. ONLY NUMBERS!!

Key Card

Used to store the codes using Key Card Maker, and open KeyCard readers.
