Music Invaders for Android just released

I am happy to announce you  that i have uploaded my new game  Music invaders is a video game inspired by Space Invaders (obviously), Audiosurf and Beat Hazzard. It is a top down space shooter where the aliens fire rate depends on the beats of your music. The graphics are retro style and will remind you the old times. There is a free and a paid version of the game. The differences is that the paid has no ads but has more enemy types, more power ups and more game modes
