New ladder backend

The ladder backend is ported to Java. After integration testing the development environment during the past few days, I feel confident enough to go live with the new backend. 1, 2, 3 live!

Players shouldn’t recognize the switch (except maybe a slightly improved performance).

Although the whole thing is written test-driven with a coverage of 93% percent and the fact that I manually tested each usecase with the current app, there might still be bugs that slipped through.

If you notice anything weird about the ladder backend, I’d be glad if you throw me a message!

And the good news: After this being done now, I have time again to add new game content. Yay!

Working on new ladder backend

I’m currently porting the ladder backend from PHP to Java.

There are a few reasons for me to do that:

  • With the root server in place, there’s no need to stick to PHP anymore
  • Better flexibility to add new features (I’m much more comfortable in Java than PHP)
  • Hands on evaluation of my use case centric open source framework JUsecase

The new ladder backend is completely open source. Feel free to checkout the github repository and see the current progress.

Big thanks to the great people at Github, Travis CI and Coveralls! You’re providing an amazing infrastructure to the open source community.

How strong is Stonecutter’s Temple?

stonecuttersThis is a question to the pro-gamers out there.

How strong is the new tower Stonecutter’s Temple in your opinion. Do you make use of it?

It has the same damage bonus effect as Shadow, so I tried to keep things low. How is your experience with it? OP or do we need a buff to keep up with darkness?

Looking forward to your opinions on this topic!

Version 1.3.0 is available on iOS

Good news for all iOS users. Version 1.3.0 is now available for iOS, too.

I’m sorry it didn’t work out for Christmas this time.

To make it up a little bit, this weekend the Black Market will once more offer Mjölnir for free.

Happy building!

Duplicate cards can be traded again

I just uploaded bugfix release 1.3.1 to Google Play, including the following fixes:

– Duplicate cards can be traded again
– The currently equipped item is not transmuted when double tapping
– Stats depending on level are calculated correctly after replacing tower
– Aura of Unlucky Pants is still effective after replacing the carrier

There are a few reported issues I could not reproduce so far. I’m still trying, but probably need more information and time. I noticed the trade duplicate issue was bugging a lot of you, so I decided to ship a bugfix update with what I have so far.

Happy building (& trading duplicates)!

PS: iOS 1.3.0 still in Apple review!.

iOS version

As you might have noticed version 1.3 for iOS is not released yet. It is still in the Apple review process, which is in idle mode during the Christmas holidays until December 29th.

This means the iOS version will probably go live beginning of January. When exactly is hard to say, cause the Apple review times are not predictable..

Anyhow, as soon as the iOS version goes live, the Christmas present will be available on the Black Market again for one weekend. This way iOS players also get the chance to fetch it. And Android players who missed it will have a second shot!

Release Notes 1.3

Done! The Christmas release is pushed to the Google Play and Apple App Store!

Don’t forget to visit the Black Market the weekend after Christmas. A free legendary item will wait for you there!

There’s a lot of other new stuff in this version:

Improved card deck usability

No longer swipe until your fingers bleed! Win every drinking contest. And get rid of unique items you do not need.

  • Double tap to transmute stack of cards
  • Long press to drink stack of potions
  • Transmute unique cards to dust

You will find notes from the developer explaining how to use the new deck features:

A mini tutorial item added to your stash.

One of three mini tutorial cards.

Dust cards

Two unique cards of any kind can be transmuted into a random dust card:


Christmas present

Don’t forget to collect it! Weekend after Christmas at the Black Market!
