Update Details:
1. New Mechanic: Luggage
When one of your buildings is destroyed for the first time in a game, a Luggage will appear to guard your territory and strike down enemies.
2. The durability of the enemy core has been decreased from 50,000 to 30,000.
3. The camera movement speed while dragging with the right mouse button has been lowered.
4. The font size of floating text for production and damage has been increased for better visibility.
5. A bug where the relic "Promotional Ad" caused buildings to be unplaceable has been fixed.
The demo version has received a lot of feedback and bug reports. Thank you all so much for your support! I will continue to release optimizations and bug-fix patches in the future!
