Excelente Juan!



This is perfection in a TZX.  Well done, as near perfect conversion as I've ever seen and love the V1.1 update. 

Excellent conversion!  Such a simple game but so addictive.

This is amazingly authentic! Best version of Space Invaders I've played on the Spectrum! \o/

I can't get the game to start. Pressing 1 on the keyboard, but nothing happens?


Hint: Press "+" (=Key "k ") to "Insert Coin" before pressing 1 or 2 to start

Thanks! I would never have figured that out.
