Llamazing ,

I have some problems

When I try to circle something I can’t. It never makes a line. Not a single line. Good... EXCEPT I CANNOT PLAY IT!!!!!! Can you fix that?

Fun and Educational!

Not only does Colony B help me learn about microbes, but it also helps scientists collect data. It’s also super addictive! I highly recommend this app!

I got the app and started to play. Great! But then it asks me to make an account. I’m thinking: Oh, okay! Easy! Nope. I made an account and BOOM! The app kicks me out! So I try again. Five times. No such luck! Awesome sounding app, teaching you about bacteria and everything. But terrible app. Hope this gets fixed..
