Thank you for letting me know about this issue and the praise.
I'll try to figure out what I can do to fix it as I've had repeated issues with that area for some strange reason.
As for your question about more being added:
Yes Chapter 1 is pretty much complete and in the demo, I don't plan to add more onto the demo but to release the game all together when it's finished for 10$ on itch.
There will be playable builds of chapter 2 and eventually 3 for patreon supporters if there's an interest for it.
Chapter 1 does kind of just peter out toward the end but that will be fixed when chapter 2 is put together.
Lost Tails is an attempt at something a bit different than my usual games I wanted it to feel more like a cartoon an adult cartoon but one that reminded me of cartoons I watched growing up, with humor and environmental/anti-war messaging, interesting characters with goofy personalities. It feels good to hear from even one person who enjoyed it. So thank you for letting us know what you thought of it and giving us feed back on a bug!
