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*
![A very difficult level. A very difficult level. Will cause more pain than joy. Avoid.](http://brianbien.com/wp-content/uploads/2010/09/jetpack-2.png)
Download the above level to play it. While there are few enemies, this level will make you think.
![jetpack Impossibly-difficult level. Avoid at all costs. Attempts to play may lead to suicidal behavior.](http://brianbien.com/wp-content/uploads/2010/09/jetpack.png)
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)

Here’s another level (above) left by Vektor. Download here.

Most difficult campaign award goes to Balmipour
Update: Balmipour (from the comments) has shared an extremely challenging campaign that will test the patience of any human. Download Balmipour’s full campaign here. Here are screenshots of the first 3 easiest levels in his campaign. To see the next levels (of increasing difficulty), you’ll just have to download the full campaign!
A new level from Balmipour!
Get ready for a “custom torture room.” Don’t try this one at home. Or do. You won’t be able to beat it, so here is the solution.
