iPhone Game UI update and small changes

Hello, We currently have an iPhone game avaliable on the app store (Link will be provided upon request) We would like to have some changes made to this app, they are listed below. We will also provide need to have the artwork created. This inclused the new UI elements and some ingame power up icons. - Add Start button at the start of the level - Add lives (3 lives per level) - Add a 'pop' annimation when the character dies. - Add a sound when a star is collected - Allow the character to float off the top of the screen and back again (gravity is already built in so you just need to remove the boundary) - Add a new tutorial pop up to first level - Group levels into 'Chapters' - Re order the levels that are already in the game. - We will tell you the oder that we want them in. - Update the current visuals to Retna display (We will provide .psd files of all the artwork so you can make it happen) - Add a store for in app purchases - Add power-ups - These will also be explained what they need to do. - Add our coin system for micro transations and buying the power-ups. - Add acheivments (we have already listed them, just need them added) We will provide a document with screenshots explaining how we would like the new UI changes to look. I will also provide another documnet explainng the In app purchases and how we want that pricing to be. One last point. We would like to form a relationship with the developer we chose. We have a lot of work that needs to be done in the future and would like to work with someone who we can trust and does a good job. Looking forward to your bids!
