I don't have an explanation of the touch controls on the site, I guess I probably should as they aren't entirely standard although I hope they're intuitive. It's a two thumb control scheme for Cave Story:

Left thumb drag (anywhere on left half of screen): D-pad

Right thumb tap/hold: shoot

Right thumb drag (any direction): jump

Tap weapon/health bar: open inventory/map menu

Swipe weapon/health bar left/right: switch weapon

For Quake, the left half of the screen works like a gamepad left stick for movement, and the right half works like a trackpad for aiming. Your weapon will start shooting automatically when an enemy is near the crosshair, even if they are not directly under it, so you need to track enemies accurately over time to score hits without wasting ammo. Tapping the top right quadrant of the screen will shoot manually, which is mostly useful for the rocket launcher. I didn't figure out a scheme to enable jumping or zoom/scope.
