Could you please put your save on pastebin.com and post the link?
You can export the save string in the settings.
When you click import it checks for your save in the clipboard and automatically loads the data. You just have to click export in the demo and import in the full game. I'm not sure why a text field would be necessary.
Is your clipboard empty after clicking export? You can paste the saved data in a text document to check.
No worries, I appreciate your feedback.
I'll take a look at the save issue. Are you using Safari to play?
Some skills definitely are underused and hard to level at the moment. I'll try to add more activities for them with the next content update and balance the loop system.
The log is not a high priority at the moment, but I want to add more messages in the future.
