Me too! This game was a chance to learn how to navigate accessing folders and how to add images/shapes dynamically (which was new for me). The bug was very annoying, but it taught me two lessons:
1) Test your export more thoroughly than "yes, a main menu screen pops up, I should be good".
2) Files in res:// are much more easily accessible in the editor than after exporting (and for good reasons).
Thanks for playing!
