## What is ba?

ba - 14th in "focus" (aa, uu, ff, au, rr, ao, rl, sp, th, ki, ci, sn, lo, ba, ov, sh, fi, do, ru & ti)

Defend the circle at all costs. Touch and hold to increase the speed of the ball, collide with dots entering to stay alive. Tap on the left side to spin left, tap on the right to spin right.

You can also top the leaderboard with your best score / longest survival. See how long you can last, as it gets progressively harder and harder.

Thanks for all your support, I hope you're enjoying the "focus" series thus far.

### 1/5 — Glitch

aa is the best app that I have ever got, and I'm on level 20 now and I only had it for 2 months. I recomed this app.😇😍🎅🏼

### 1/5 — Not good

*2015-06-30*

This is not good

### 3/5 — It won't let me tap?

*2015-06-21, version 1.0.1*

This game is really fun and provides a modern spin on a classic game. I really like it, and think it's one of the best in the focus series. The only thing is, it won't register my taps sometimes! I lose an average of 3 lives per round because of it. One minute I'm playing fine, the next it stops spinning no matter how many times or how hard I tap! Then it suddenly starts up again, after I've lost a life or two. I don't know if this is a problem with how I'm playing (tap and hold one side to spin one way, the other side to spin the other way) but it's really annoying me. It would be cool if you guys could take a look and see if it's a problem or if it's just me? Thanks.

### 3/5 — Legal
