A delightful game integrating sight and sound, ARC is a game of chain-reactions and music-making that will likely go directly into your Favorites list.
Stars on a circular orbit will appear and float randomly on the play field. Click on a star, quick-drag and release to 'throw' it around its orbit. Timing becomes important to collide with other stars thereby causing a one-revolution "blast." Other stars that come in contact with a blasting star will also blast, and hence begin a reaction chain.
There are three (3) different modes of play: Accelerated, Accumulated and Training. In Accelerated play, the objective is to create the longest chain of collisions possible, which the game keeps track of as your only score; there is no time limit to play. In Accumulated, you have a limited number of stars (100) with which to accumulate the largest score possible, with each collision in a chain worth increasingly more points. Training is merely an opportunity to play with slower stars without the confines of the other modes, and it offers very little feedback to warrant any real time spent within it. You might as well jump right in and start playing for scores.
Analysis: I love unique games like this. The elegant simplicity with which ARC blends audio and visual stimuli with interactivity is like sweets for the senses. Although there is not much depth to its gameplay, the casual nature of what it does offer rewards those who come back often. I wish the click-drag mechanic was just a bit more effortless to control, as it becomes frustrating at times to get the stars to behave as you might like. Simply wonderful.
A separate page is host to the High Score list.
Cheers to Graeme for suggesting this one for JIG. =)
