I pushed a hotfix a few days ago to add more checkpoints, I'm sad that it ended up preventing you from finishing the demo!
I have pushed another patch just now that addresses that, but since I have been moving on with ambience tests, it might not run as smoothly.
I'm really glad you like Isobella, even in her early state - there's a lot more work to bring her to life ahead.
We'll add a glyphs-per-second option to the settings, as well as force "Enter" to proceed any tutorial dialogue, I think.
All your other feedback makes sense, we'll start working through it. Thank you for playtesting, it helps a lot!
