It seems things got a bit stuck. How can I unstuck the game?

Thank you for your response, I have tried reloading the game to no success and unfortunately hitting "Export Save" doesn't do anything, nothing gets copied to clipboard nor does a file gets created. It's okay, it's one of those bugs that happens with development. You have a fantastic game here so far. I hope you keep developing it, it's one of the best incremental games I've seen on this website.
