Challenge Go (aka Challengo / Ray's Challenge) is an action/puzzle game set in an expansive world, inspired by classic block-pushing games like Chip's Challenge and Sokoban. Originally released in 2006, it was quickly featured on the YoYoGames Sandbox where it went on to receive over 30,000 unique downloads. It has since gone through numerous major developments. The latest revamp adds touchscreen controls and sees its expansion to additional platforms. An online high-score system per level allows you to compete against others for the best time. Secrets galore including cheat codes and hidden areas. The goal in Challenge Go is simple: fight your way through each level to the portal to reach the next area. Get lost in forests, swamps, deserts. Walk over the sky in ever-changing weather and light, and even navigate the depths of space. Sneak through cursed ruins, war zones, dark labyrinths and haunted houses. Use items to run faster, open doors, pass hazards, and destroy. 100 levels total to challenge even the most dexterous.

STABILIZE THE CONSOLE. BEAT THE COUNTDOWN. Your infrastructure is collapsing in real time. "System Overload" drops you directly into the hot seat of an industrial telemetry dashboard failing under heavy stress. There are no gimmicks or visual distractions here-just a cold, clinical control panel, a fast-draining clock, and unstable recovery modules demanding your immediate attention. Can you maintain absolute focus, or will you overload under the pressure?

Verdict
The clearest difference is ads: Challenge Go at none against System Overload's shown. Challenge Go also leads on device support (4 vs 2) and iOS requirement (10 vs 17.0). On price and in-app purchases there is nothing between them.
