Nuclearoids is a chain reaction arcade game that will remind you a little of Boomshine. A collaboration between GameBalance (Warp Forest, Orbox) and Alexander Samarin, expect a whole lot of smooth color changes and great visual effects to go along with your physics-based orb collisions. It's a game of not-quite-controlled chaos that takes a big step in the webtoy direction.
Move the cursor around the field and hover over a viable explosion spot. Notice the trails that get pushed off the nuclearoids? Those indicate where the orbs will go and at what velocity after you cause that grand explosion. Orbs ricochet wildly and collide faster than you can keep track of, all with a glowing color change oscillating before your eyes. Try to knock around as many nuclearoids as you can with that click, as that's all you get to clear the target number to complete the level.
You'll notice a lot of little physics things go on while the nuclearoids are bouncing around the screen. Larger orbs attract smaller ones, often enticing them into orbit before they stick/collide. Black holes do pretty much what you think they would do, only in this universe, you can destroy them, which is kind of a power rush.
Nuclearoids creates a beautiful little mess of chaos that's like eating an entire bag of Halloween candy... with your eyes! In the gaming department, however, it suffers a bit, as you have very little control over what goes on after you make that fateful click. There's some strategy to be had with pushing certain orbs towards groups of orbs or other objects, but in the end, it's pretty random, so it's as much luck as it is planning. Because the presentation is so engrossing, though, it's a lot of fun to sit back and watch things interact.
Put some bright colors in front of your eyes and make some 'splosions with your mouse. You know you want to!
