Petri is coloring game by Matthew Gillingham. $0.99
Petri is a simple game where you must color in the screen a certain color to get to the next level. Its quite a fun little game but I couldn't stand playing it for long periods of time as it got very repetitive. With 100 levels to complete it will take a good half an hour to complete all of them, I managed to get my time down to about 20 seconds per level.
The graphics are good. They are bright and do their job. Nothing extra could really be done with the game graphics wise without putting the price up. I don't think it should be done as the gameplay isn't really worth more than the 99 cents. The game responds quite well when it is touched. Sometimes it doesn't remove the colors when it is on the edge of the screen but no major problems.
I could have really enjoyed the background music to this game. It has a fun, up beat tempo but I believe it has been ruined by a high pitched sound that goes off all the time. The sound has nothing to do with the game and I believe it should be removed as it is quite horrid.
As I said before, it is quite a simple game. The controls are very simple, tap and/or drag your finger around the screen to remove all colors from the screen and double tap to add color to the screen. I found this quite easy to master after a couple of go's by just removing all color and continue removing it until the color required popped up on one of the edges. Each level has a slightly different pattern to work with, such as a pixelated level or the colors were in the shape of diamonds. Each level also would say the color required to fill the screen with at the bottom right hand corner, sometimes this is hard to see as the font is the color required. There is no high scores table yet for fastest times and I would like to see this.
Overall it is a very polished game. There isn't much of a replay factor in the game as I believe that it would get very repetitive after 100 or 200 levels. A quick and fun pick up and play game and one that is at least worth considering.
I would recommend this game if you enjoyed- 7 Colors
