Decipher Quest

Decipher Quest is a puzzle game based on a simple geometric substitution cipher.

Story
You are the roboter Fred. You live with your robot family on a nice little planet. One day a Space Blob appears. He has a cryptic language and wants to destroy your world.
Your only chance (weapon) is to decipher his language to talk and convince him to not destory your planet.

How to play
Drag and Drop the highlighted card-letters onto the darker ones. The Space Blobs language uses a simple geometric substitution cipher. You have to find equivalent characters or symbols to form useful words.

When you think you are ready, press Fred to read or send a decoded message.

BEWARE: If you cipher or decipher wrong, Fred and your planet gets damaged from the Space Blobs laserbeam! Fred has only 10 chances!

Press 'p' or 'esc' to pause.

About
The whole game was made during the Ludum Dare 32 in 48 hours by me.

Tip 1:
Memorize the ciphers when letter to pigpen.

Tip 2:
The latin alphabet has an order. The pigpen ciphers have the same order.

Tip 3:
The cipher is also used in the mainmenu and the gameover screen.
