Jim's World: Adventure Games

Mushrooms make you stronger, monsters make you dead, and that push-your-luck gap between the two is why Jim's World hooks you fast. This old-school running game drops you into a jungle level, and the second you clear one super boss you're already tapping to start the next run.

The setup is simple and a little cheeky: the Princess got kidnapped, Jim's World has been empty ever since, and now it's on you to sprint Jim through the jungle to get her back. Jump the obstacles, dodge the evil monsters, eat what makes you stronger, and grab every coin along the way.

Those coins and bonus items aren't just for show - spend them in-store on extra items to help Jim survive the next stretch of jungle. Add the well-designed levels and the enemy variety, and it's easy to see why this counts among the site's Rescue Games.

If you're already sold on jumping over things that want you dead, Deadly Descent and Stick Merge are worth a look too. Jim's World plays free in the browser on desktop, Android or iOS, no download needed.

Get Jim through the jungle in one piece and rescue the Princess from the monsters holding her. Every level throws obstacles, enemies and a boss fight at you, and reaching the end is the whole point.

Use the on-screen buttons to jump, move and fire at whatever's in your way. Eat mushrooms and other items as you find them - they make Jim stronger and better equipped to take down the tougher monsters.

Don't skip the coins and bonus items scattered through each level. They rack up points and let you buy extra gear in-store, which makes the next run noticeably easier.
