Thanks for the review! Glad you enjoyed it, even if your first run was a bit short. The key does spawn randomly in one of the shiny loot spots. We initially wanted to add a bit of a story to make it longer but ran out of time. I'm working on a patch to update the game but I'm thinking to wait until the ratings are done. In the spirit of the jam I'd prefer to have what was submitted be what's rated, but after that I'm hoping to get those in.
Thanks again for playing! And stay posted ^_^
