Any color keys

The mod adds several new concrete doors and corresponding keys to open them. Currently, there are 6 door colors available: red, yellow, green, lime, blue, and a secret door. The lock is an item required to create locked doors. Keys are needed to open doors. There are two types of doors: regular doors that open like normal doors, and locked doors that can only be opened with the corresponding key. The mod also includes a variety of Easter eggs and achievements, so be sure to explore them all.
