Robby Superhero Obby packs a full blocky obby game into a single browser page — press play and you are in. 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. It is also unblocked here, so it runs fine on school or office networks.
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. Give yourself a round or two to warm up — the difficulty ramps up quicker than it looks.
