Lots a great games at this price point, but the very best $.99 I gave ever spent in the app store was on Hook World by rocketcat games. Loved Super Quick Hook when it came out, when I got to the avalanche level, I kept going back to that.... So much so I never even finished the game! (still need to revisit that one ) Anyways, a year or so later, they came out with Hook Worlds... Holy crap, it's like four games in one. Love being chased, knowing your time is limited, but still pushing as far as you can. I don't ever feel like the game cheated, when I die... It always feels like it was my fault. IMHO, thats hard to do in a random world game. Second would be a dead three way tie!! Cough cough, JetPack joyride (jumped opening day,) Minataur Rescue, and last but not least.... Gridrunner!!!
