Oh yes that could be it. Glad you got it working. What do you think? Enjoying the update?
Yeah its good, liking the new levels. Maybe in a future update you should let people buy stamina with BCY though.
That's one for the team, if you are on Slack you can suggest that.
The reason for the stamina is, like in other similar games, that otherwise players could get bored easily if they are allowed play the game continuously.
This way you play a little then have a break then play a bit more. I don't think the time to recharge the stamina is written in stone either so it may change depending on feedback.
