Ever tried speedrunning Sonic the Hedgehog on the Genesis? This challenge throws you into the classic blue blur’s first adventure with one goal: beat the whole game in 30 days. No saves, no rewinds—just you, those loop-de-loops, and Dr. Robotnik’s ridiculous contraptions.

First few minutes feel familiar—Green Hill Zone’s music kicks in, you’re rolling through loops, grabbing rings… then you realize you actually have to learn the level layouts instead of just winging it. Those underwater sections? Way more stressful when you’re racing the clock. And good luck with Marble Zone’s lava puzzles without memorizing the timing.

It’s brutal but weirdly satisfying when you shave seconds off your best time. Just don’t throw your controller when you miss a jump in Labyrinth Zone—again. The Genesis sound effects will haunt you.
