I like the Rescue Team series, nice look to the graphics, challenging and fun. Found this one very addictive and it took me a while to complete all 50 (yes 50!) levels. Small criticism, there wasn't a huge variance in the scenarios but it kept my interest.
I like time management games and have played stacks like this one but this one takes the biscuit! (pun intended) The graphics are poor and I played it for about 60 seconds before I deleted it. don't bother - there are plenty of other very similar format games on here that are much, much better
