Like a normal iPad! Tap on the apps to use them. In photos, tap on the current photo to view the next photo. With crossy road, use the arrow keys to move the chicken around and try to get to the taco without getting hit by a car. You can't take photos on camera but you can view yourself if you allow scratch to use your camera.
I might make some more apps on this project. Have fun and sorry about the glitches!
