Edit/Create artifacts for game display in the ECCO lobby
The files in /lobby-artifacts need to be made to match the game. The files in there now are examples from other games -- try to keep the length/format similar for each. Please see commit 182d135e1e05dfc99dc4d997bdcce3e849796c1e.
The "thumbnail.png" is the main icon that represents the game in the lobby.
