Nerdy Bird is the indiegame developer name of Jens-Christian Seele. It was created due to the development of the draw game "Doodle" in 2011. The last project realized by Nerdy Bird is "Sonar". Though Nerdy Bird is a semi-professional project for game development because of fun and not of career or money, there is no need for any more core devs at the moment. But if you are interested in joining escpecially for creating graphics or other media content or for 3D-coding, feel free to contact me. If there is a new project, I will mail you back ;)
After Desura went offline some time ago and indievania even a lot earlier, you may enjoy the full and uncut version of SONAR (v.1.1) now for free :)
The second demo of SONAR, containing 2 Levels and nearly every single gameplay element.
