Customer Reviews

A good game but..

They aren't as mean on the surface like companies that make you pay to keep playing, this one makes it so hard to play that you need to spend money on upgrades in order to continue. Still quite Ahole ish IMO.

Update: I've decided to up the rating to 4 stars because the developer was kind enough to respond to my previous review. It's pretty awesome this still happens and they take the time to do so. They also have given good tips which I hope will get me past level 46. Even though they called me not smart, which is correct, I appreciate the challenge and Criticism given back. :-)


Love this game and the new version! Maybe just as important, had a glitch that was bugging me so I contacted support. Over the course of a week and at least half a dozen messages, the developers went out of their way to help. They adhered to the highest possible standards for customer support so if I could give them 10 stars I would. Looking forward to this and other future apps of theirs as a result!

Reminds me of the old arcade days

This game reminds me of the old arcade days. I think it's pretty fun. I've spent a lot of time playing it and it took me a while to finish but when I did it was a good feeling. The best part is being able to upgrade your ship, the old arcade games didn't really have this ability so I really like that. Also there are no 'lives' you can keep trying and playing as long as you'd like, no 'game over'. My 2 cents anyway.
