less jumppads

and "TheAdster" u should hit 1 before playing it keeps the timing right and the level play consistant

Firstly, you die a different way each time, without going all the way round. This level has soo many faults, lasers hitting you too early, you bounce off of springs differently each time, you hit thwumps etc. One time I even froze in an upside down ragdoll position.
Secondly, there's a rocket at the top. To get rid of this, search through the save code for an NaN. This is, for want of a better word, a glitch. When you find it, delete all of this code: 10^300,NaN! Make sure it is not the code for the chaingun, however, which looks like this: 6^756,36,3,0,2,NaN!. Hopefully, the rocket should be gone.
Thirdly, this is the mistake absolutely everyone makes on their 1st DDA: cut down on the springs. Mine had so many I called it Spring City! :P I know you know how to use alernative propulsion (that sounds oddly posh...) as you have included both trap door and thwump propulsion. However, I think you have only used them once each. Add some of them to get some variety in, otherwise you will be hounded when you submit the completed version.

Hope all this helps, and hope the finished level is great!
