### 1/5 — Literally does not work

*2026-05-20, version 2.6.1*

Played the tutorial, registered, it quit. Opened it back up, entered login credentials, it quit once I pressed login. Opened it back up, clicked Guest, it quit.

### 4/5 — Why do I need a title if it says optional oh this has nothing to do with this app

*2025-03-31, version 2.6.1*

Uh why is there only like six reviews it makes the game look bad.anyway my class is doing a science unit and we’re using this app good for surviving at school no offence and I don’t like punctuation so yeah it’s okay it’s for science class

### 2/5 — Good Idea, Buggy Execution

*2025-02-26, version 2.6.1*

I think the idea is great, and the world would be a better place if people spent more time making games that improved the world or the mind, ideally both. But it’s too bad that this attempt turned out so poorly. The main issues so far in my experience, have been some crashing issues when the game goes into the background mid “level” and then tries to come back and start again. Then there is the UX issue of the score lingering too long after you circle the bacterial bundle, which blocks the next set of bacteria. Then on top of all of this is the unclear point of the game, the intro does pretty good, then the actual game doesn’t play the same after that. Then there is the issue of the log-in screen. It doesn’t make it super clear when you have successfully registered, then if you have and you forget the password or mistyped the password (because there isn’t a double check when registering, i.e. type the password again, or the option to make the password visible.) you then have issues because no email is actually sent to reset the password (probably because the service is no longer being paid for I would guess.)

### 2/5 — Needs a bit of work

*2022-09-11, version 2.6.1*

I was super excited to help out with a scientific study but the app crashes every time I try to do anything. It let me do the training but after when I try to log in/register or even play as guest it crashes. I am unable to help kinda disappointed:(

### 3/5 — crashes a bit too often

*2021-08-13, version 2.6.1*

game has crashed when i’ve played and when trying to send an email to myself to reset a password

### 3/5 — Not Impressed So Far

*2019-08-14, version 2.5.1*

Sure, helping with a huge scientific study is neat. But the app shuts down each time I finish one set, and it seems determined to Not save my language preference (English, BTW; I know French, but it’s not my primary language).

### 1/5 — Horrible

*2019-04-03, version 2.5.1*

Can’t play! Kicks me out when I try to play.

### 1/5 — Kicks me out after first attempt at playing

*2018-12-16, version 2.5.1*

App kicks me out of the game after circling the cells.  Does it each time I try to play.  Not very encouraging.

### 1/5 — Annoying

*2018-02-27, version 2.2.3*

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..

### 5/5 — Fun and Educational!

*2018-01-20, version 2.2.3*

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!
