The mobile version of Prison Architect is cheaper with a price of $5.99 for architect mode. It sadly does not include Escape mode but may some day be added in. It is just as fun as the full game but doesn't include some features.
The layout of the screen can be a bit confusing. It has all of the objects, rooms, emergency services and destruction in the bottom right corner. On the right side, you have your burocracy menu and other stuff. On the top you can see the time, weather, day, and money.
Playing the game is like playing normal prison architect. One thing I noticed was when you are building, you have to press the button again to get rid of the green building area. The game runs smoothly and can be used offline. Have fun managing your prison. Report bugs to the developer and make sure you have fun!
