Last night, I was hunting for new apps on my iPhone 4s and came across this gem.
I only have the Lite version, but I was entranced into playing for hours. Its comparable to being in a tiny Tetris Sim center
In this game, your goal is to resuscitate the old, young, and very sick. A nice touch is the option to use the cardiac and FAST ultrasound while running the code.
The complete version is $1.99, a very tolerable price. Enjoy!
