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. Will cause more pain than joy. Avoid.
Download the above level to play it*
Impossibly-difficult level. Avoid at all costs. Attempts to play may lead to suicidal behavior.
If you really want to play the level above, here it is. It’s fun*
