No installs and no paywalls: Obby: Parkour with Ragdoll is a blocky obby game that starts the second you hit play. It captures the obby formula perfectly: colourful blocky worlds, tricky courses and constant progression. Touch controls are supported, so you can pick it up on mobile without losing anything. And because it is hosted on LemonArcade, it stays unblocked on school networks and Chromebooks.
Make your way through the course, grab the rewards along the way and upgrade your character to go further. On mobile, the on-screen touch controls take over — joystick — move. A couple of practice runs will teach you more than any instructions.
