Sorry Peps,
I ran a little late for my hourly report. I ran into a little problem getting the actual x,y coordinates of the invaders within the group. I found the method to resolve it but it cost me a some time. So my latest PUSh includes:
Timed Space Invaders firing (with bug)
Tank firing on touch of background with blast
Latest screenshot (too bad I couldn’t capture the missle blast in the screenshot):

See ya in 60
