Thank you so much for your message. Those speech bubbles were a lot of work to place, I'm glad you like them. I appreciate you telling me, it means the world to me.
Regarding the end of the chapter: you've basically reached the end of the available content. Someone else on patreon also mentioned being stuck here, what should happen is the End Screen should show and you get back to the Main Menu. I kinda added that in but have not released that patch yet. But yeah, that's the end for now.
