Is that Glitch All + Blast Pure door supposed to make an impassable chasm once opened? KeyTool's infinite jumps glitch (basically, doors are treated as ground even once they're destroyed, allowing you to jump infinitely as long as you're touching a location a door once was) allows you to cross the chasm anyways, but I suspect that's not intended, and I'd like to make sure that using said glitch is not part of the solution.

EDIT: I finished the level, and I’d say this was a really good puzzle. Use ROT13 to decode my following comments:

Solved V4 just now. Very neat puzzle, although quite dastardly as well, especially with all the number crunching I had to work out. My solution ended up not using the Combo Brown+Pure or the Brown Exact -1. Not sure if I got an alt or if those were meant as some form of anti-cheese. If the latter though, then I might be able to implement a cleaner version of it into the game using some new mechanics from Part 2.

For posterity, my solution was (rot13) Terra Erq Checyr Oyhr (Plna Oynfg) Oynpx (Cher +1) Juvgr Tyvgpu Oebja Cvax Benatr
