Customer Reviews

Great for this genre!

I read one review where the guy says 1st mode is like Lumines, the 2nd mode is like Super Puzzle Fighter. Not to mention that this is now free, it's definitely worth a try.
Those modes are LIKE the respective games, but are different.

Radioactive (1st mode) has you group the things together and how many varies by color. The 2nd mode has slightly different circles that act as 'crash gems' which will burst those of the same color, but number does not matter like in 1st mode.

Visually, I feel like the 'Next' box keeps tricking me because I group the circles as a clump of six instead if two and two and two... A small space between each pair would help? Crash 'gems' or balls whatever are fuller circles and can be difficult to see, but I guess no helping that.

By the way, I played this in the same day I was playing Lumines for iPod. BAD IDEA. Or at least, it took me time to adjust from Lumines' crappy controls. The arrows are a nice touch for accuracy, but if there was a way to work in the alternate rotation (on the other side? Maybe move the down arrow, or put the rotation buttons next to eack other?) that would be sweet.

Great job on this. Oh, and ability to select color blind? Nice touch.

Please fix the scoring cap also, I'm sure that will be a factor in the future ;) Global scoring is cool, but not the most necessary thing

cool little game, very addictive

nice graphics and sound. the gameplay is very innovative and addictive. there are lots of different backgrounds and sound tracks. I especially like the big buttons on the display. it is very satisfying when I make a huge combo. the best feature that I like is the game auto saves the state of the game when I exit. I don't loose any progress when I just play the game for 5 minutes. I wish the game play area can be bigger so I can make more massive combos, but still, a great game indeed.

The BEST iPhone game!

This is the 1st review I have ever written, but this game demands accolades. After downloading & subsequently deleting over 50 games, this is the only one I still play regularly. Awesome look, very original, stylish. Even the music is great goes so well with the gameplay. The gameplay itself is the true marvel, though. Simple, yet incredibly intuitive & FUN! Cannot give enough praise. EXCELLENT!!!!!!
