Yay, I'm so glad you enjoyed it! :)
There will be about 6-8 episodes (each having about three chapters each) or about 45 minutes of content each (not including puzzles, just story content). About six endings are set in stone, but there may be more. The next couple of episodes require me to make a lot of the background art that will be used in the latter parts of the game, so these episodes will take longer than the rest of the episodes to release.
