I finally got around to playing this! I played Project Kat literally 4 years ago (insane how fast 4 years go by) but the entire time I constantly remembered my time with it and would occasionally check in for when Paper Lily was releasing.
Funny enough, when I was playing Project Kat, I saw it was made in Godot, and since then I've learned a bit of Godot myself with interests in game development.
This game has been a treat to see come to life and finally get to play!!! I'm so excited to go through the entire thing and savour it. Also the music is incredible. I love the change that happens when "this is when the search truly begins"
Here's my playthrough for anyone interested!
