Thanks so much for playing! I'm glad you enjoyed the demo.
The "Sleep Mode" is actually June setting her phone back to silent, and attempting to fall back asleep. Most of the active game play with take place within her dream, while her time awake will be reflecting on the dream and events that led up to this night.... Though I haven't decided 100% yet. I have most of the game planned out, and there will be some variety to the gameplay throughout!
I hope you'll check out the full version when it's ready. I can't promise it'll be soon (I have a lot of projects on-going DX ) but I do plan to finish this story.
