Thanks, i am glad you enjoyed but you did not have to tell me 3 times ;)
About the e i added an extra outline so it would pop more i gather that it wasn't sufficient? (i didn't want to make a to big change)
About the sounds, i use an addon called Dialogic, the sounds come from there, but i checked and they are apparently by "Typing sound effects by Tim Krief". If you want to see the code is at https://github.com/dialogic-godot/dialogic Hope that helps
