This isn't a bad idea, it just needs some developing. For one - a start screen. A given number of lives, and maybe think about upgrades (greater range of vision, maybe stealth or camouflage) and a backstory... who are all these people? Why are you shooting them? I think this game can be improved but it definitely isn't a bad start. 3/5
The music and graphics were one of the only things that kept me glued to the screen, despite my increasing levels of frustration. Damn you, NoxiousHamster. (but you are an excellent developer. 4/5)
Not only was this one of the most original games I have played on Kongregate, it was also interesting enough to keep me playing to find out everyone's secrets and achieve the best possible ending. Although I think the characters could have a little more depth to them, which I am hoping will appear in the sequel. For now 4/5 and favorited.
Although I'd like to be able to move the entire line by clicking anywhere inside it, rather than just the edges, this game still deserves a 5/5, mainly because it calms me.
