Thanks for the info, downloading it now.

DRM free, without so much as a serial. Just download, install, and you're done.

They email you a download link. It gets sent to whatever email you registered on PayPal.
That threw me for a loop since I don't use the email I have on paypal anymore, and they make it a pain to change it.
But after you download it, it's DRM free. No key or anything.

Better you than most people, to be honest.

Thanks, although DRM really doesn't bother me too much with games like this. is the download link always active, do I have a limited number of downloads (before I either need to repurchase, or request a new link), or what?
I ask because I already have so many things to back up before reformats that I really don't want to add another item to that list. Plus, I tend to play indie games on my laptop (just feels right), but I also might want to play on my desktop (and my usb drive is already full :p).

Unlimited downloads (they ARE indie devs, after all), so keep that email you get from the automated bot thing. Choose your download, and it will link you to ANOTHER temporary link to download (so you can't spread the link around, obviously). Pretty safe. You'll be fine.

Judging by the fact that the servers are limping along and nearly dying every so often thanks to the billion zillion visits by people who are also interested, I'd say it doesn't matter how much you'd pay anyway.

Ok, then ;)

Hmm, after playing the demo I thought that I might pay $10 for it but $20 was too much. Might see if I have the cash left after bils this week

Did someone noticed how long this prono is actual? It's only for today? Site is offline now.

Wow, that's a great offer. I paid $5 for a subscription to this title from Steam, so this is a great way for me to get it for a few bucks and own it.
Great title, I had a blast playing it. Warning for completionists tho...some of the OCD challenges are maddening.

i think it lasts for 5 or 6 days

You know what is amazing, is I put a post in the forums that I own the Steam version of the game and wanted to know if I could convert it over to a stand alone version of the game, or simply get a discount on an additional full copy of the game.
I never even received a reply, and now they offer the game for whatever you want to pay; blah. At this point I am inclined to think it is worth nearly nothing since I already bought it and could not even get a single response to my post.

Bought it, but the servers have crashed so I can't download it. Gee, never knew the demand for this game was so high. £20 (the RRP in the UK) though is pretty damn expensive...I mean that's $30.
