Hi, We have developed a game in Unity, called 'Fishy Finger' Please see video of game here - [login to view URL] GAME OVERVIEW 01 - Strategy: The idea of the game is to use your finger to swim through the water avoiding the barrels 02 - 3 Minutes: If you last 3 minutes, the game is over and you have cleared it. 03 - Obstacles: there is barrels in the water which you must avoid (swim around)... if you hit a barrel you will die... also if you lift your finger off the screen, the fish will come out of the water and you will also die 04 - Coins: collect coins as you swim through the water to build up your score 05 - Levels: The game is split over 3 levels which are 1 minute each 06 - Speed: The speed of the fish gets faster as each level progresses 07 - Animal: an animal jumps over the water in each level BUT it does not touch or kill you (it's just to distract you) WORK REQUIRED We are looking for a long term Unity developer who will work with us to finish this game and work with us on new games. 01 - Performance: maximise the performance of the game so it works on lower end phones 02 - Google Ads: help us add Google Rewarded Ads into the game 03 - Onboarding: add onboarding of user and sync with their phonebook so that your friends who have the game show in the leaderboard PLEASE READ BEFORE BIDDING (IMPORTANT) If you are going to bid on this project please reply with the following, as otherwise your bid will be ignored: 01 - a link to a game you have developed in Unity 02 - do you have experience adding Ads to games 03 - how will you maximise the performance of our game I look forward to working with you.
