Traffic Jam for Windows 8 passes 100,000 downloads

I made some updates recently to Traffic Jam for Windows 8 and it recently hit 100,000 downloads! It’s getting about 500 downloads/day now which is respectable. 
For comparison, Super Picross for Windows Phone is at about 40 downloads/day yet it produces more ad revenue than any of my other games. The ‘daily puzzles’ are what keep people coming back to the app.

Traffic passes 400,000 downloads!

Traffic just hit 400,000 downloads on February 5! Window Phone 8 has definitely helped boost downloads, I’m getting close to 800 a day again after dropping quite a bit.

Super Picross hasn’t had nearly as many downloads but it seems to get almost as many ad impressions. The Daily Puzzle feature is great for getting people using the app regularly. It’s a lot of fun playing the submitted levels too.

Ads aren’t paying very well anymore so 2012 wasn’t quite as successful as 2011. However my apps still have a good place in the windows phone market which is growing everyday. It’s also my 29th birthday and I’m quite happy 🙂

Updates and Vacation!

It’s been great to get reviews for Super Picross from people who are enjoying the daily puzzles! The list of puzzles is getting quite large, to the point where I need to make an update to organize them better. It’s on my list of things to do, as well as some ports to windows 8. 

With that in mind, I am taking 2 weeks off work to go to Tanzania! Thankfully there are enough daily puzzle submissions that I can set them in advance and not worry about it.

Super Picross v1.0 Released!

Download Super Picross

My 3rd game Super Picross just got released to the WP7 marketplace!

If you’ve never played Picross/Griddlers before it can be as addictive as sudoku and in my opinion much more awesome. I’m a big fan of logic games and I wasn’t satisfied with the current Picross games in the market so I made my own.

The big challenge with Picross games is that the phone screen isn’t big enough for large puzzles so to keep it all touch controlled there has to be a zoom feature. I modeled the zoom feature off Pixelogic for iPhone, dynamically resizing the grid to focus on a 5×5 section. I think it works pretty well but it might take some getting used to.

There’s only 24 levels in the original release but I’m hoping the daily puzzles will make up for it. There’s a level creator and submission system so each day I’ll be adding a new puzzle. I’m getting bored with playing my own levels so I want to try some of yours :).

Please send me your comments/feedback


Traffic 2.1 released

I added 60 more levels to Traffic and fixed some bugs. The game should be available in a lot more countries now once their marketplaces open. There was an annoying bug where the application settings were getting cleared, and this caused the review prompt to appear multiple times for some people. I removed the crash reporting by email since Microsoft shares crash reports to developers now. I also updated the advertisement control to use the latest SDK.

Traffic passes 200000 downloads


It took a while, but Traffic passed 200,000 downloads on July 16!

You can probably see that the downloads/day has decreased a lot. I think this can be attributed to the limited user base of Windows Phone, it’s almost impossible to maintain 1000+ downloads/day unless there are new users to keep downloading your app. Once there are some new phones released hopefully the downloads will pick up again.

I haven’t been developing at home much recently because of some problems getting the Mango tools installed (not enough space left on my windows partition). I just reinstalled windows and visual studio and I’m hoping to get some work done this weekend. I will hopefully release some new levels in the next week.

Traffic 2.0 released!

Since a few people have said they finished every level I thought it was time for an update. Traffic 2.0 has 120 more levels! Some of these are more difficult than any of the original levels.

The other big change is that levels use a star ranking now, with 3 stars for a perfect score. I thought my original design was getting overly complicated with stars, check marks and borders. The graphics are also slightly improved, the vehicles have softer colors and some of the uglier colored vehicles are gone. The red car is now a convertible!

I added a notification asking for a review after the 10th time you start the game, I’m hoping this will get more quality reviews in the midst of all the spam.

Let me know what you think! I am still working on another game and have been making good progress recently. I’d like to update Slideout as well but the downloads for it haven’t been that great recently.

Traffic 1.3 released! :) (and some talk about privacy)

I hope you enjoy the latest update to Traffic, I added support for basic themes. The Smile theme was something I coded a while ago as a joke but I finally decided to put it in the game :).

I get the occasional user concerned about why my games require owner identity, data connection and web browser. The web browser is so I can link to this blog, the owner identity and data connection are used by the advertisement. How do you know that I’m not taking your data and selling it? Well one reason is because I have no motivation to (I’m making plenty off ads), the other is because it’s all anonymous data.

Apps get the “Owner Identity” requirement (ID_CAP_IDENTITY_USER) when they use the UserExtendedProperties Class. The only supported property available from this class is “ANID” (see MSDN).  This property is for getting your “Anonymous Windows Live ID” so that you can be identified uniquely by the app. It’s quite possible that Microsoft’s advertising recognizes your phone from other apps you’ve used but it doesn’t actually have any personal information. If any of this information is incorrect please let me know :).

Microsoft’s advertising also has the ability to use your GPS coordinates to target advertising based on where you live, but only if the app has “Location Services” enabled and shares this information. This is what my games used to do but I removed it when some users complained, I can understand why it’s a privacy issue.

Thanks for giving me your feedback!


Traffic 1.1 released (and download stats)

I finally released an update to Traffic. I addressed some of the complaints about the stars being too small and changed some of the levels that were very similar. I didn’t realize that GTLevel (the level generator I used) will actually repeat levels once the move counts get too high. I think this is because there is a much smaller number of original levels with total move count over 35 so repeats happen more frequently.

I updated the UI slightly to follow the WP7 guidelines better (24 pixels from the left, etc). I considered putting in more time to improve graphics and maybe add sound effects but I’m not sure how much this will actually improve the game. So let me know, would you enjoy playing these games more if there was better graphics and sound? Would you rather I work on new games or on improving my existing games?

I’ll share some of my data to give others an idea of how often my apps gets downloaded:

In total Traffic had 78569 total downloads at the end of February, 20667 in January and 57902 in February. About 68% of the downloads are in the US market.

In the US market Traffic reached the top 10 on February 2, peaked at #6 and is currently at #7 . Slideout broke the top 100 in late February and has been around #90 for a week now.

Like many independent WP7 developers I reached the conclusion that free games with advertisements are the best option. The ad revenue from Microsoft’s ad control has been great so I don’t think there is a good reason to make a paid version of my games. I know some people are willing to pay 99 cents not to see ads and I’m sorry that this isn’t possible. I don’t want to release a separate paid version since any user switching from free to paid would lose all their progress. I could use the trial API instead but I want my games to stay in the free section of the marketplace since this is where most people look for games. Hopefully the trial API will change in the future so it becomes a better option.

I made some changes to the ads in version 1.1 to test more categories and change the ad frequency. The data is starting to come in, I’ll make a blog post about it in a few weeks when I have more to report.

Again, thank you for supporting my apps and leaving positive reviews! I do read your reviews and appreciate your feedback.
