I don't know how it will play out on GOG but based on their faqs and what said in a kickstarter update the game will be splitted in 3 games, one for each campaign.
Shovel Knight originally featured one campaing, with Shovel Knight ($15). Later it was added a second campaign featuring Plague Knight as free content. In April another campaign will be released featuring Spectre Knight.
Tomorrow the original Shovel Knight will be rised in price (25$) and will became Treasure Trove, that will contain all the three campaign (the last will be added in April). The three campaign will also be available as a standalone game a the price of $9.99. I don't know if it will happens right away, I know that Spectre of Torment will be out first on Nintendo Switch.

Based on the price, I suggest to purchase now the game for 9.99.

Are you guys psychic in regards to ending all of your sales a few hours before I get paid?

Great, the discount didn't even last long enough for me to get home from work and buy it. :(

How about 24 hours at least so that everyone worldwide has the chance to get it for the discounted price???

As far as I can tell the new campaign that is already with the game isn't actually new levels, it is just a different class unlocked to play through with. That is fine and something a lot of games provide as freebies to new and existing customers to increase sales or cross-promote.

Heck Dungeon of endless from one of my fav devs added 4 new characters from TF2 in a free update and it impressed me enough I bought the dlc I was missing from the game with a smile.

To call things separate campaigns though does seem like someone is overselling what they actually did. The truth is what they are actually doing is providing a couple of extra classes and basically the same levels (which they promised to their kickstarter backers anyway).

The standalones just seem to be cut downs versions of the regular game and a rather feeble justification for a price rise.

Perhaps some customers are OK with it, others who have the game already are no doubt delighted about another class coming out to play through with.

I'm not going to judge anyone who bought it or is completely OK with what the dev is doing or anyone who is not OK with it.

My own opinion is I think they oversold what they are offering and frankly I will just buy stuff from companies who are more straight forward and upfront about what they are doing it and why.

I must concur with the request for a better notice. The notice was only given 8 hours ago... While I would have been sleeping.

The sale ended about an hour prior to your post, so it's back to $14.99. Doesn't matter to me as I have no interest in the game.
As for the rest, I guess that people interested in this game will have to wait and see how things pun out on GOG.

As I said, it's within their right to sell whatever content they create, but don't claim to be releasing free content for all players.

To be fair, this whole thing made me uninterested. I don't have a whole lot of money but the sale both appearing AND disappearing while I was asleep... And now I missed out on the sale. What, was I supposed to be up all hours of the night?

I don't know who's decision it was to tease me like this, either GOG's or YCG's, but this sale flying right by me because I have a sleep cycle, coupled together with a price hike, all that serves only to disinterest me completely from purchasing the game. I feel like I'd be subsidizing anyone who bought it for less by making it viable for them to continue making 'free but higher base price' updates.

So I guess my loyalty card for 'more free' costs more? No thanks...

On the last phrase you are right. Let's say they put the emphasis on the good side of the deal while give less importance to the rest.
The free new content is indeed for the old customers (although the game is also receiving an update in its content that will be for all players).

Didn't you realize we were on the internet? Specifically the GOG forum? That's a lot of people's pastime for all I can tell. I'm amazed that our regular negative Nancy, Zoidberg, is actually not among that crowd for a change.

This game has been on my wishlist for a long time but a price increase doesn't really encourage me to buy it. Seems unlikely it ever will have a deeper discount so for that reason it's off my wishlist.

You've actually been here longer than a lot of people mister[bye, PewDiePie; fuck this, fuck that at the end of everyone's threads]mumbles.

I don't know what the first example has to do with anything. Having a bit of schadenfreude at the expense of an imbecile Youtuber is hardly worth admonishing. The other was just a stupid outburst (regarding the World Cup), which I even bothered to edit out completely shortly thereafter, that hasn't occurred before or since. Compare that to the frequent shit I see others doing... Yeah.

That content was free for previous owners of Shovel Knight, who were only buying one or two campaigns when they did it, as a thank you.

Because they've essentially been making content for free for the past 2 years or so, the full package has undergone a price hike, for the new buyers, who unlike the old ones who put their faith on the company, will be buying all three campaigns right from the get go.

I don't see anything wrong here.

If they had charged for the extra campaigns from the get go, it would undeniably be worse, yet no one would be complaining about it today. That's punishing the devs for ever being generous in the first place.

Nice to give us a heads up about a price increase and offer a discount before the price increases, but you should have given it at least a 24 hours time frame.
