About Petri

Petri
Android Game

In Petri you attempt to grow a cell culture in a Petri dish. You deposit individual 'good' cells which grow and divide, spreading across the dish. However, 'bad' cells appear from the ambient environment which you must battle for control of the dish. You can use agar to speed up your cells or fight off the bad cells with numerous tools like lasers, temperature-control, penicillin, radiation, bleach or intentional phage infections. Additionally, spontaneous phage infections can occur which may threaten to wipe our your colony. You must fight those off as well.

Level progression is divided into 'stages', where each stage consists of a series of 'rounds'. Increasing stages indicate increasing difficulty while the rounds within a stage provide variations in gameplay (by varying the round's end-condition and the possible bonuses such that different strategies and approaches are required for each round).

Lastly, an online global scoreboard lets you show off your success to the whole world! This scoreboard is available either through the app or at http://petri.keithwiley.com.

Petri should provide high 'replayability' since there are no secrets. Just keep trying to improve on your earlier high scores (or try to beat other people's high scores for dominance of the global scoreboard).

Awesome game. Much props to the creator. So unique and fun but the game freezes on me to often like when I start a new level or exit the game and come back to it. If it wasn't freezing on me it wld def b a 5 star game

Viruses occur too frequently you can never keep the cell culture healthy.

I love it to pieces. Just a great game for any science nut or really anyone who likes fun little games to pass the time. I love how you answer comments and legitimately try to fix issues and listen to your players. 10/10 would phage again. Also, the best part was my antivirus software checked it after I downloaded again and said it was virus free... Well, it certainly has a lot of bacteria! Haha

But interface and overall UX needs to be thoroughly and thoughtfully redesigned. Now app isn't user-friendly, like, at all. But the idea itself has Top-10 potential. UPD: I don't mean the mechanics of the game level, it's actually among the things that make the game interesting, unique and playable. What I don't like, though, is the style of graphics itself. Lose the pseudorealistic textures (or make them look convincing), change fonts, change numerical stats with progress bars or something. Make buttons flat, unify icon styles. That's what I mean. Also, the way the game progress is saved is inconvenient.

I love this idea. Very challenging trying to kill off only the cells you don't want. I'm just not fasr enough.

Great gameifed fun with artificial life in a petri dish. What's more, experimentation doesn't require messing with any gross E. coli, either. My favorite tools/weapons of bacterial destruction are: (1) irradiation (2) lasers (3) bleach Personally, I learned about some bio lab techniques and had gem fun while doing it. Thanks for writing and releasing this app!

This app has tons of challenges and levels. There are just the right amount of elements in gameplay--more than enough to be interesting and different with each play, but not so many to be confusing and and overwhelming. Works flawlessly and looks great on my tablet! Thanks!

This is utterly fantastic. I'm more of a chem than a bio nut, but so much fun, and has a ton of actual scientific references. Bam.

A great game well worth your time! Constructive feedback- I want a sandbox mode!!! Also I would love a campaign mode where there are scenarios to progress through, with a limited amount of abilities and more specific objectives. For example maybe penicillin appears randomly, you can't adjust the temperature, have no bleach and have to survive. I would love modes where your goal is to develop resistances rather than just score extra points for them. But it's a great game!

Works very well on nexus 7 4.3. Improvements: add labels to the tools because I kept forgetting what they were

Lots of fun! I usually use the lasers to zap away all the bad and unhealthy cells. It's fun to play around with the different tools and watch the cells do their thing.

This game is fantastic and challenging. Bit of a learning curve but its nice to have an app that has some substance. Would be great if the menu and text gui's was a lil nicer and the tutorial was abridged. The gameplay looks and runs great though.
