I have this hey bug. So, I tried to go to window mode, didn't help. Also tried using different compitability mode (win8 mode, playing on win10). And I quickly ran through all the chapters using choose day option. Other chaps also have the bug. Chapter 2 - it writes heyo and nothing happens after. Chapter 3 - leaves a blank bubble and writes nothing. Chapter 4 delivers a picture, becoming blue bubble, then nothing happens. Chapter 5 - message is delivered, then nothing happens. Last chapter gives you 2 grey messages, after jumping through them to your potential message bubble it does nothing. Hope this helps somehow! The design intrigues me!
