Game Update, May 2023:

Changed: Safe mode has 3 settings now. 1. Wait at day end. 2. Doubletap to open treasure chests. 3. Prevent tossing away towers.
Changed: Silver treasure chest has 70 swaps again. Gold has 380. Swaps will only be reduced when a new item is added to the game to make it easier to beat old scores.
Fixed: Social links.

Note on iPhone if you want to play a podcast at the same time as tower swap, you have to unmute sound/music then mute them again then play the podcast again.
