Really fun game, I love playing it. It’s like it’s own new sport, and it’s super competitive. The AI (yes, it is AI), is definitely smart, or random enough to provide a real challenge. There’s a bunch of potential for a really really fun game.
There are a few things that could really make this app a solid 5-stars. First, to simply be able to change your color would be nice. I like blue, but I like orange more. Having a ton of colors to choose from too would be really nice. Second, it would be really really nice to play actual people, and for rankings to actually matter (the more you win, the more skilled your opponents get). Third, and most important, please... please stop the incessant vibrating every single time anybody moves an inch. I get the idea, but I seriously can hardly stand playing it now.
