Credits and licences

DISCADE is built with the work of many open-source projects. Thank you to all of them. The game shows the full licence texts in Settings › Licenses.

Art, sound and levels

Every sound effect and piece of music was synthesised for the game. Every graphic, from the board and discs to the ten world scenes and the app icon, is drawn in code for the game. Every level was generated and checked by the game's own tools. No third-party art or sound is used.
