The problem is that the textures (indirectly) originate from websites with optical illusions, and depending on whether these can be called common knowledge or not, they are free to use or not. For example, given how many different variants of rotsnake you find on images.google.com, that one can probably be called common knowledge, otherwise there would not be so many differently colored and angled variants of it. The map may be illegal, but if it is, remaking the textures in any way won't fix it.
Do you use Nexuiz 2.1? The lava pit jumppad requires at least that version. But I can increase the jump height if needed.
BTW, I am curious what ways there are to reach the Strength... the Shield can be reached by a VERY lucky laser jump, but for the Strength I haven't yet found a way without using a rocket jump. But maybe it is possible to reach it from the orange corner slope using a laser jump, I never succeeded in that, but it may be possible.
Well, and the map was an attempt at making the "worst map ever" after some person apparently took that "award" from me (look at the images on the concave walls to find out a parody on whose maps it is...

) he may be blue but not amused about it. Hopefully he will not throw me off das tower...
1. Open Notepad
2. Paste: ÿþMSMSMS
3. Save
4. Open the file in Notepad again
You can vary the number of "MS", so you can clearly see it's MS which is causing it.
