Magic Cookies! released for iOS
After a few weeks adapting testing, and preparing the game for iPhone and iPad, we have released our Haskell game Magic Cookies for iOS on the Appstore. You can also find the Android version here.

Haskell on Android and iOS
We strongly believe that Haskell is one of the best choices for game and app programming. It’s declarative, it’s portable and it’s robust.
However, turning your Haskell code into an app that can be published on the App Store or Google Play for Android has always been painful.

Magic Cookies released on Google Play
We are pleased to announce that Magic Cookies! is now available on Google Play. The rules are simple: your objective is to remove all the cookies from the tray, but be careful: touching any position on the tray will toggle it, and also the one above, below, to the left and to the right.

Shake your lambdas with Haskell and Kinect
A new version of the game Haskanoid, with Kinect support, has just been made available.

More Haskell games, graphic adventure engine, running on Android
We are extremely happy to announce that we now have several Haskell games working on Android, including our Graphic Adventure engine. Also, we have just begun beta-testing one of the games with real users via Google Play (aka. the Android Market).

Par thy Android - A short followup on "60 FPS to 500"
Last week we published a blog post briefly outlining several steps of optimization of a Haskell game. In the article, the last two steps, which referred to parallelism and concurrency respectively, were inverted, making it sound like the Android version was using the parallel library.

From 60 Frames per Second to 500 in Haskell
Haskell is often advertised as fast, easy to parallelize and to optimize. But how much of that is really true? We are going to demonstrate it using a game we are building, including how many changes we had to introduce to increase the game speed by 700% on desktop, how we managed to go from increasing memory consumption in the order of hundreds of megabytes down to constant memory consumption of only 3MB. We’ll also see the impact it had on Android.

Declarative Game Programming -- slides, videos and code
Earlier this month, Henrik Nilsson & Ivan Perez presented a tutorial at PPDP 14 on Declarative Game Programming.
The goal was to show how real game programming is possible in a purely functional, declarative way. One way of doing so, seeing games as networks of interconnected signals and signal transformers, results in clear, reusable, modular code.
To illustrate these ideas, a small but realistic game was demonstrated, featuring many of the complex elements found in arcade games: SDL graphics and sound, Wiimote controller, and differentiated subsystems for rendering and sound, game input, physics/collisions, game logic, etc. The game has several levels, each with its own background and music.
To help others interested in functional game programming, all the talk material have been made available, including the slides and the full game code.

A new version of Yampa is out (0.9.6)
Yampa is an impressive, arrowized, Functional Reactive Programming (FRP) implementation written in Haskell. We are using it to implement Android games at Keera Studios, and it has been used, among others, to implement the video game Frag (see video below).

The most inspiring green screen you will ever see
While Haskell, Idris and other Functional Programming (FP) languages enable writing elegant code, the road to production is, well, bumpy. Writing code for industrial environments has added costs that make certain products too expensive and infeasible in practice.
