You need to upload all those individual files as one zip folder. I had to download the 5 downloads here independently and unzip the two zip files to get it to run.
As for the game itself, it's kind of fun! I liked the level where I had to push a block to block off the connection to the purple ball. I think it crashed after 4-5 levels. I got to a point where hitting "again" or "next level" didn't work.
