Ok, I changed some stuff:

Nerfed the railgunners a bit. They still do all the same stuff except they now drop $250 instead of $60, they come in smaller numbers (unlike the sand people) and they don’t try and dodge walls.

Nerfed the pipebomb guys a bit. They drop $100 now, up from $60.

Made the portal particles purple so they stand out against a white background.

Made the win text less vulgar.

Made the achievements a bit more logical. The spanner doesn’t count as a weapon anymore, and you can’t get the no structures achievement unless you NEVER build a structure in the area (selling them all before the end won’t work anymore).

You can preserve your progress by overriding the “config.ini” in the new version with the “config.ini” from the old version. Checkpoint saves won’t copy over though.
