GI:Similar to other endless runners (like Temple Run), Iron Man flies through the air dodging blimps, billboards, and missiles as he collects tokens. Tilting your device to guide Iron Man through these obstacles feels smooth and responsive. However, you also have the added challenge of shooting down enemy drones by tapping or swiping your touchscreen. The controls are simple, but that makes the game incredibly easy to pick up and play for a few minutes. Challenges like “reach 10,000 meters in a single run” or “collect 200 credits” give you plenty of carrots to chase. Daily challenges function like boss battles, where players have to reach a certain distance and then battle a powerful enemy before being rewarded with a pile of credits.
