Finally, after a week or so of battling it out with the Google Cloud verification team Reflex is available on the Google Play store.
The Android version is identical visually to the Windows version except you play by tapping the game board and dragging the screen around with your finger. The Android version also supports vibrations for when a missile is destroyed (can be turned off); it also supports Google Achievements.
The game can be purchased from the store by clicking here.
