Hey I've been wondering, does only Richard have bonus scenes or will the other guys too? I've only been able to read Richard's bonus scene. If it helps I'm on Android, I dunno if the other routes are implemented since I've lost track of the updates and I'm unsure if it's a bug.

I guess you are talking about Harold and not about Richard. It's his epilogue. Currently it is available through main menu, but Dyne said that in future you will access it only if you ended his route on the "best" ending. And soon our faithful dog will also receive his epilogue, and it gonna be heartmelting no less than Harold's epilogue
