INTERESTING.
It's doing all the right stuff, but it seems to not be Spawning the upgrade cards.
It's supposed to pause the game and give you 3 upgrade cards to choose from (only 33% of glitches do so). You cannot pause or move until you choose a card so that's why you're freezing.
The only idea I have rn is perhaps the cards are showing up UNDER the orange banner due to Sprite Render Order. I could look into that and upload a new patch, but I think that would be against the rules of the game jam?
