My favorite app on my iPod touch was Tap Tap revoultion.
So I was a little bit disapointet when I could't find a good rhythm game for android.
Becaus I was interested in Android-programming, I decided to write my own version.
The result is Neon Rhythm.
It's a little bit like Guitar Herro or Tap Tap. But I added an Editor, so everyone is able to make his own tracks. You can place different targets on your screen and record a track. This alows you to make many different tracks different Tracks.
With the last update I addet Multitoch, Tap and Hold and a limited track download funktion.
Furthermore I made a "Pro" version that allows you to upload your Tracks, download tracks without a limit and you get a advanced editor.
I hope some of you like my game and/or give me some feedback.
