About this game

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).

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.

It's directly UI. You move the lasers by dragging them to their new locations. You deposit objects on the dish by tapping directly where you want them. Some types can even be "finger-painted" directly across the dish. This is a very direct UI. How could it be easier, if I may ask. Thanks for the encouragement btw. Glad you like the overall idea.

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

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!
