Doors & Keys

## Description

If you've ever opened a door in your life, then you're completely qualified to play this simple, frustrating, and outright addicting game!

Doors:
1) You are presented with two colored doors. One is locked and the other is unlocked.
2) Tap a door to open it. If it's locked, game over. If it's unlocked, you advance to the next level!
3) Repeat.

Keys:
Every 5th level has two doors of the same color. Both are unlocked, but one has a colored key behind it. If you get the key, it sits in your key inventory until you tap on a locked door of that color. The key will unlock that door and disappear from you inventory. You can earn keys by sharing Doors & Keys on social media or by visiting the Doors & Keys Store.

The Skeleton Key: This is a very special key that requires the 4-solt upgrade. Once you have a Skeleton Key, you can automatically unlock any locked door if you don't already have its key. The best part is, the Skeleton Key lasts for five unlocks!
