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.

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.

Video Ads


If I could get rid of the video ads I would keep playing it. At least for a bit. I'm not going to assume paying money will do that. Not when some developers take money and remove ads or ad banners but keep the ad videos. Shouldn't be surprised by anything some of this FREEMIUM games do.
