The game includes a simple level editor. Numerous levels have been published on Adept Software's website. The registered game features 100 pre-built levels. The developers also released a hintbook containing screenshots and a short piece of advice for every level.
Jetpack was released in several variations, including a Christmas version, where the player became Santa and ran around collecting presents instead of emeralds. The Christmas version was almost exactly the same, with different levels and a few more festive sprites. There was also a version designed for younger children.
