Fun and Creative

Just as the title says this game is absolutely amazing to play with as a fun time cruncher. I hope new updates for this game release new levels and challenges alike.

So Good... blast to play!

I can't believe it. This game is amazing. Nostalgic, but with great graphics.

When I played Atari's Missle Command on iPhone, I was surprised by how much better it was in my memories! 😜

This game is exactly the look, feel and fun I would have thought vintage Missle Command would have been. Happy I found it! So FUN!

Fun but waves are a bit too long

Fun game with a really great look and feel to it. The music is especially nice also. But for what is essentially an arcade shooter variation, the waves drone on for far too long. The difficulty ramps up a little too steep too. If that was tweaked a bit this would be a five star game for me, but as is only gets a three from me.

Developer Response ,

The game is now balanced and more levels along with new challenges added. Thank you for your suggestions.
