- Undo now takes back only your last action instead of reverting state completely
- Selling is blocked while in build mode
- Dragging out a row of towers is much smoother
- Crystals settle down while you build and come alive when the round starts
- The build timer now waits for the story dialogue to finish
- Pressing build with no supply tells you why instead of showing a ghost tower
