Make sure your build is checked as "windows" otherwise it will show up as "game is unavailable" on its page. Trying it now, That voiceover is cute, and following the red mountains was fun, but then having to listen to the one in the dark was annoying :p (when it says hold D to skip)
Also level 3 seemed downright impossible given the high amount of enemies, and then I fell down the world edge and it didn't kill me so I just fell indefinitely and then quit the game.
Also another thing, I am pretty sure you don't own the rights to the windwaker's dragon roost island theme or yoshi's island theme either :p
Other than that game was fun for the first 2 levels!
