Hello! I'll say "yes, but..." Some of the art and audio assets I used are royalty-free ones I've personally obtained through various bundle sales, so they cannot be used as is due to the licensing. However, either I could be involved, at least peripherally, with the Community Game and thus the assets can be used as is through me, or the assets could easily be recreated by members of the Community Game team and disconnect the game from the royalty-free assets (which I'd recommend in general :) ).
Would any Speedgame entry chosen be built on top of the existing codebase, or would it be started from scratch and mainly focus on replicating and expanding on the game design, mechanics, and aesthetic?
