How Can I Test The Tap Screen Controller On Pc ?

I can only use keyboard to control the character in BB? How can I test the tap screen controller on PC (or any simulator for that?) ?

Thanks for your kindly help..

 

Click a left mouse button damn it!

 

Thank u.
But it I'd like to test the "drag-and-drop" actions with 2 players..... how should I do on PC ???
Many thanks..

 

Left click and drag with your mouse? If that doesn't work then it won't work on mobile either
