Hi guys!
Need help with this! Iām doing some attempts of games, and I just export the 1st one for android. How can I add the instruction for the touch screen? Currently Iām using the arrows of the keyboards + Mouse to shoot!
Any help will be appreciated 
Check the last events in the Web Platformer template (located in the Templates folder inside the GD root folder). Instead keyboard, use some sprites as buttons, and check if you do a click (or touch) over the buttons to move 
You have other options too, for example move at right when touching the right half of the screen, or any system feasible through touches
