OVERVIEW Collider is a sweet puzzle game that easily deserves 4-5 stars. The game mixes the concept of science and gaming together to make an addicting physics puzzler. The point is simple, drop the neutrons (negatively charged atoms), and the protons (positively charged atoms), and also the uncharged bases to cancel out all the others. If a neutron touches a proton, they both explode. There is a labyrinth of pipes and tubes to chute it through. GRAPHICS The graphics are grungy to give the pipes and chutes a rusted feel. There is one argument I have though, the graphics are extremely pixely and rough. I was honestly expecting more from it. GAMEPLAY Simple and fun gameplay would be two words to describe this. Simply drag the few atoms and then press play to set them rollin'. Not much more here to talk about. MUSIC/SOUNDS The music is lacking a bit but the effects sounds are spot on. You can turn off the music quickly too so you can listen to your iPod. RATINGS This is my honest ratings of one to ten GRAPHICS: 6/10. REPLAY VALUE: 8.5/10 MUSIC/SOUND: 4/10. INTEREST LEVEL: 8.5/10 OVERALL: 8.5/10 It is a great game easily worth $0.99 and should be bought immediately.
