In a previous jam, we had a game breaking bug riiiiight at the end of the game that caused it to crash. After a futile attempt to fix it, we ended up just wrapping the whole game in a try-catch block. When the game crashed, it just took you back to the title screen. Thankfully, the game was hard enough that only a couple people made it to the end, but they had some funny reactions.
We hit an issue right before submission with this game that almost got us to do the same thing, but we thankfully didn't have to resort to that. Though, I won't promise our game is perfect by any means XD https://itch.io/jam/gmtk-2019/rate/460345
