We launched a DRM-free, cross-platform (Windows, Mac, Linux), Alpha version of MouseCraft and sold it through our website. Here's the Alpha launch video:

We made the game available for free, for all those who registered into our Beta Program.

We submitted the game to Steam Greenlight.

We came up with a rather innovative way of selling our game - everyone can get the full version of MouseCraft for how much they feel the game is worth. No "beat the average price" to get the bonuses (OST and future Steam/GOG/Desura keys).

We made our sales statistics visible for everyone, all the numbers, OS stats and top contributors are there.

The average price was about 3,30$, and the highest contribution was 112 dollars.

More sales = lower average price.

People interested in the game and not just "making a deal" contributed more.

Positive reviews from major gaming sites and personalities (Rock Paper Shotgun article or Jesse Cox's video) have not resulted in massive sales.

MouseCraft Alpha sales numbers are hardly a success, hardly a failure.
It surely would have been a disaster for us, if it were the final game sales, but if you bear in mind that these are, in fact, pre-orders and MouseCraft wasn’t available on Steam, then the whole thing is starting to look pretty ok as pre-orders are usually 10 to 20 percent of the final sales.

Our "allocate your funds to particular game features" experiment was a success.
People gave us more than they had to, and some of them contributed serious amounts of money to see the game updated the way they want to. Also, it made us really stand out in the huge number of indie games published these days.

Positive press coverage doesn’t guarantee massive sales.
The significance of press articles is getting smaller every year - their opinions can be a great social proof, but it is Reddit, YouTube and Twitter which can bring crowds to your website.

Getting on Steam is not always only about upvotes.
If you have a good game and you think it is being “treated unfairly on Greenlight” because of its genre – try reaching out to Valve.
Try writing them an email or create a blog post that will get noticed. Even better- go on Gamescom, E3 or GDC and storm into their booth to show them your game. We have done all of these things, and I think it was one of the reasons why we got greenlit.

Your game's genre can be your enemy - be prepared or die.
Marketing your PC game or your Greenlight campaign can be extremely challenging if your game is a puzzler. Even if it is fairly difficult, has no microtransactions and highly references classic PC puzzle games like Lemmings or The Incredible Machine, it will still be frequently treated as a mobile, iOS/Android game. Don't fight it, you will surely lose...
Instead, try focusing on the features that will make you stand out from mobile games. We done that by emphasizing our Level Editor feature and our community-oriented alpha-funding process, which would be impossible to run at mobile devices.

We will be updating MouseCraft with some of the features that have been chosen and funded by our community.

We call it a Co-creation Update and you can expect it to include new levels, placed in a completely new graphic theme and inspired by the maps that we received from our community. There will also be a new Tetromino brick, a good-looking game map and some bugfixes.

Steam Early Access.
Thanks to being greenlit we will be able to publish MouseCraft to Steam's Early Access program. The game will stay there until it is fully finished. During that time, MouseCraft will definitely get updated a few times and will be integrated with all the Steamworks features (Leaderboards, Achievements, Trading Cards and Cloud Saves). We are also thinking about posting it to Desura, but we haven’t made a decision yet.

Keys to redeem the game on Steam.
MouseCraft website states: "Receive all the perks by default - no need to beat the average price. Included : Soundtrack and Steam keys." We will of course live up to this promise - everyone who bought the game by now will receive free Steam keys, no matter what was their contribution.

We are sticking to our Give-What-You-Feel model, but...
...we have to make a price point for receiving the Steam keys as it is impossible to sell the game on Steam without a set price. The possibility of getting MouseCraft for a dollar or two would be really unfair to all the people who bought the game on Steam for a set price.

NotOnSteamSale The good news is we will be giving the Steam keys to all the contributors until Wednesday (9th of October), because of the ongoing Not On Steam Sale we're in. So do not linger- get MouseCraft along with Steam keys for how much you feel they're worth: http://mouse-craft.com/store.
