Jetpack: anyone remember playing this 15-year-old DOS-based game? You could build your own levels where you navigate through mazes. I uploaded a couple of my own, created years ago for your enjoyment*

Download the above level to play it. While there are few enemies, this level will make you think.

Impossibly-difficult level. Avoid at all costs. Attempts to play may lead to suicidal behavior. — Impossibly-difficult level. Avoid at all costs. By playing this level, you agree to accept full responsibility for your altered sanity.

If you really want to play the level above, here it is. Don’t be fooled by the lack of enemies, and get ready to have your patience tested – or, just give up now and avoid the pain! (updated 10/14/12 to fix a cheat)
