This game consists of code, data, images, and audio. All of the game's art and audio assets, with the exception of the music tracks, are under the license described in ASSET_LICENSE.TXT - you can basically do anything with them as long as you share your changes. The game's music tracks are under the license described in MUSIC_LICENSE.TXT - you can share and copy them, but not make modifications or use them for commercial purposes. Everything else is under the license described in CODE_LICENSE.TXT - it's the GPL 3.0. In layman's terms, this game is fully open source, including for commercial purposes, with the exception of the Music Tracks. Our musician will allow you to use those in your version of the game ONLY if it's non-commercial and if you attribute him. If you replace the music tracks you can do pretty much whatever you want. The only other restriction is that if you make any changes, you also have to share those changes, regardless of whether you are using this for commercial purposes or not. Read each license for attribution information. Read notes.rtf before you start. Good luck! CellGame - an open source fork of the original CellCraft game (www.cellcraftgame.com)
