• Earn coins for your performance, and spend them in the SpisMall.
• Unlock over 80 separate Worlds, and dozens of other items, from bonus abilities and playable characters to arcade games and artwork!
• Over 200 unique enemy types which you can fight, have assisting you, ride on, run away from, and scan for information!
• Let’s repeat this one: over 1,000 levels to play!!
• New level types like Stealth where you must remain hidden, and Underwater, where you have to maintain your oxygen levels.
• An incredibly powerful, but easy to use, World Editor is built into the game – it’s the exact tool we used to create the original levels, not some watered down garbage!
• Over 400 more worlds available in the Workshop, featuring more than 5,000 more levels. You know when procedurally-generated games say things like "over 3 million levels!"? This is like that, except they’re all handmade (by a collection of dedicated fans throughout the decades)!
• More hours of gameplay than it is possible to shake a stick at, given current technology*

Originally released in 2003, and now enhanced for Steam for its 20th anniversary! Featuring achievements, Steam Cloud support, full Steam Deck support, and the Steam Workshop for custom levels.

* Even 20 years later, stick technology has not advanced to the point where you can shake a stick at the hours of gameplay.
