Create iPhone and Android app soft of like Flappy Bird on Steroids

THIS IS A REPOSTED PROJECT, WITH ADDITIONAL CONDITIONS. PLEASE READ CAREFULLY BEFORE BIDDING! We are seeking an experienced Freelancer to DESIGN AND CODE a mobile game app for iPHONE iOS and ANDROID, and deploy to The App Store and Google Play. The developed app will have the "tap-tap" functionality of Flappy Bird, but not much else. This game app will involve the use of gravity, accelerometer, SPIROMETRY, and will be MULTILEVEL (5 screens of 20 levels each) and MULTIPLAYER, with in-app purchases and on-screen advertising (with option to eliminate ads by paying for app). Like the original (Vietnamese) Flappy Bird, our game app must be fairly hard to beat. WE DO NOT HAVE FRAMEWIRES, BUT DETAILS WILL BE PRIVATELY PROMPTLY PROVIDED TO BIDDING FREELANCERS WHO SIGN A NON-DISCLOSURE AGREEMENT (“NDA”) WHICH WE WILL HANDOUT AFTER RECEIVING INITIAL BIDS. You will need to design everything from scratch, including actors, scenes, backgrounds, etc. You will also have to provide us with a DEMO of your previous 3D experience, whether Game Salad, Unity 3d, or other game engine and, if you are shortlisted, we may use TeamView as a safeguard measure to verify that you have shown us your own actual work, and not simply given us links to someone else's website or app store apps. WE WANT A 3D GAME APP. You are bidding to develop a 3D game app. If you were shortlisted previously for this project, and are still interested in being considered for the award, please submit a new bid conditioned upon your agreement to our explicit new terms below, of NO ADVANCE MILESTONE RELEASE. PLEASE TAKE CAREFUL NOTE THAT WE WILL NOT ENTERTAIN ANY BIDS WHATSOEVER REQUIRING THE RELEASE OF AN ADVANCE OR INITIAL MILESTONE. If you require an advance milestone, please do NOT waste your time and ours bidding on this project because if you are awarded, we will quickly cancel without giving you an advance on Freelancer.com or initial payment via Paypal. We will deposit a reasonable milestone with Freelancer.com, but WE WILL NOT PAY ANY MILESTONES PRIOR TO RECEIPT OF FULLY SATISFACTORY COMPLETE 3D DESIGNS AND UI FRAMEWIRES. We have been scammed on TWO PRIOR projects. Freelancer SOFTERBDX from Bangladesh, formerly known as XCODELOKI, stole our funds after award and did zero work before his XCODELOKI account was cancelled. Freelancer OFFENDERSTECHNO of India also sought and was given a sizeable advance milestone and, after 30 days, has produced no useful designs and zero code, and has ceased communication with us, causing us to lose our funds again (we will be leaving extremely unfavorable feedback for OffendersTechno, as we did for SofterBdx, to warn other employers to avoid these scam artists). ONCE AGAIN, WE ARE A REPUTABLE EMPLOYER LOOKING FOR AN HONEST, EXPERIENCED DEVELOPER TO BUILD OUR APPS. We have a Clash of Clans type game app and a Fantasy game app which we may award to the Freelancer who successfully handles this project.
