Tailbound: Classic is currently the only public build available. It is not representative of the final game in any way, as it is nearly 2 years old, and is only a relic of the early design/plot I had laid out. I have a full walkthrough of the game written here, which is helpful considering how cryptic some of the puzzles are. This version of the game is currently free, however I might unlist it once the game is finished to avoid future confusion
