noticing a glitch where the notes appear at places closer and closer to the hit line until i can't see them appearing before they reach it. Longer maps are unfortunately unplayable. Enjoyable when it doesn't do that though! Excited for chapter 5 maps!

Yes it's a glitch caused by too much lag. The next update will have a re-write of the note spawning code that should fix that. Until then there's a few things you can do that should help prevent it. Assuming you're playing the browser version, make sure graphics acceleration is on in your browser's settings. If you're using Firefox, try a Chrome (or another Chromium based browser), as Firefox has issues with Godot web games unfortunately. If that doesn't fix it, the downloadable version should have better performance, making this less likely
