You need to make the file executable.

Did you unzip it? I know people who say "It doesn't work!!!" and haven't unzipped it.

Guys, I think he's talking about downloading other peoples' creations.

You need to MAKE (compile) it
on linux:
$ cd directory-where-is-tpt-mod
$ make

after, you need to make it executable
$ chmod +x ./powdertoy-executable
or if this dont works
$ sudo chmod +x ./powdertoy-executable

so, you need to RUN it:
$ ./powderoyexecutable

P.S.:$ represents the linux prompt (so do not type this)
sorry for my bad english
