Alone

You wouldn't believe the amount of fun I had with it :).
Could you please add the option of skipping the earlier levels? Replaying them over and over again gets tedious...

Thank for comment.
I can change it. Good idea

That's what I call a funny little game. ^^

I had fun playing it too ! Could not beat level 3

I gave up at level 5 or so, but it was very fun to play. Well done.

Even though it's very simple, it's pretty fun! I got to level 7. I couldn't understand how come when you shoot your shot disappears and instead a new shot appears. Also, the dialog that shows when you lose was a bit annoying. But the main idea is nice, hope you continue to develop it, and the way the circles move after you is also nice.

The windows link takes me to a page in German, where all the links names "download" just open pop-up ads :-(

You should use something like mediafire or drop the $15 for some legit hosting. All of those download links take me to something that isn't your game.

Can't download this, as mentioned by other commenters. There are several 'download' links on the page you've linked to but none of them allow me to actually download the game, they just redirect to other random sites or pop up ads.

If you don't have your own webspace, Dropbox is a good way to make your games available for Ludum Dare, since it actually works properly and doesn't bombard downloaders with ads.

Cant only have ubuntu box

Sorry I can't play, I don't have a Windows machine here.

Can't download it from the site, the "download" button just takes me to the homepage of file-upload.net
As other suggested, Dropbox would be a good alternative.
