Idle Sand Castle

Do you like digging? Do you like sand castles? You came to the right place.
In this idle game you will feel all the pain when your castle is destroyed.
The famous Sandman puts the one oh his mines at your disposal.
Dig the sand with your own hands, dig deeper. Then hire miners for faster progress. The larger the mine, the more miners are available.
From time to time miners want to rest, but they haven't a lot of time. Be like a real BOSS, don't let them sleep at the workplace
Boost the miners' efficiency. Improve the endurance and physical strength of your employees. More then 60 levels of improvements are available.
Create a sand castle of 30+ level with the height of a skyscraper. Get crazy money from tourists for selfies with the castle. Develop tourism to the maximum.
But do not forget that your success is already being watched by attackers. Don't let them destroy your castle.
Push them away, it's fun. If you can't do it on your own, hire a security guard. Improve the guards' weapon, namely the distance and reloading of the shocker.
Not everyone is able to achieve the goal, but I believe in you.
Good luck)
