The issue with the crashing after the level is a known issue, and is fixed on my local. It isn't crashing, per se, but let's just say I made a change to the pause mode of a node without testing it, and it ended up affecting the win screen as well.. Found the issue after submission, but figured it wasn't necessarily game-breaking, since it didn't show up until after the level was complete, so I just called it out in the comments of the page.
Thank you for your feedback!
