Develop a Cross Platform Trivia app for Android, Windows Phone and IOS.

Hi. My colleague and I need a trivia RPG app template which we can use continuously for a franchise. The trivia app template should be robust enough for these features: 1. Must be able to sustain over 500 questions. 2. Must have a Score system based on Difficulty levels and a Timer system and excellent documentation. 3. Must be Auto-Rotate enabled and have support for Splash and Loading Screens. 4. Must have support for In-Game BGMs and Sound Cues for Buttons and Effects. 5. Must have both a local In-game Leaderboard and Google Leaderboards. 6. Must successfully and efficiently integrate online In-App Purchases in an In-game Store. 7. Must support varying levels of Difficulties for the trivia questions - Easy, Medium, Hard, Extreme. 8. Must support timed events and the manipulation of time with the special abilities. 9. Must support randomization of the questions as well as their options so that every time the player plays the game, the sequence of questions always changes. Special Abilities Abilities are particular to select avatars. The Avatars have a Total Energy display, which the abilities draw their Energy Requirements from. Each ability must have a Cooldown, a Number of Uses and an Energy Requirement. When the player begins, the Total Energy is also visible. 1. For Ability 'A': If the player selects an answer, he can click on 'A' instead of the 'Next' button, and if he is right in his selection, his score is increased according to the difficulty of the question, with the Easy difficulty with the highest bonus, instead of just getting the normal score for that difficulty level, all without changing the question. 2. For Ability 'B': It reduces the cooldowns and energy requirements of two other abilities. 3. For Ability 'C': It mirrors any random ability already purchased. 4. For Ability 'D': It changes the question without any score penalty to the player. 5. For Ability 'E': It answers the question correctly, updates the player's score, and then changes the question. 6. For Ability 'F': It stops the timer for a few seconds. 7. For Ability 'G': It decreases the cooldown of 'H' and increases the uses of 'H'. 8. For Ability 'H': It awards bonus points to the score according to the difficulty level, with the Extreme difficulty receiving the highest bonus, if the selected answer is correct and 'H' is clicked on instead of the 'Next' button. Regardless of whether it's correct or not, it changes the question. 9. For Ability 'I': It has the potential to warp away one wrong option every time it is used. Can be used multiple times for the same question. The first time it is used, there's a 100% chance to warp away an incorrect option. consequent tries for the same question reduce the chances of success by half exponentially. 10. For Ability 'J': If the selected answer is correct, and 'J' is clicked on instead of 'Next', bonus points are awarded to the score based on the difficulty, with the Hard difficulty getting the highest bonus points. If the answer is incorrect, more time is added to the timer, all without changing the question. 11. For Ability 'K': It changes the difficulty of the question randomly every time it is used. Can be used multiple times for the same question. If a question is on Easy difficulty, and 'K' is used, no matter how many more times 'K' is used, the question will never be on the Easy difficulty again during that play session. Same applies to the other difficulty levels. 12. For Ability 'L': It checks if the player's score is greater or equal to 300, 600, 900 or above 900 at the moment "L" is clicked on. Depending on the result, bonus marks are added to the score from 350 to 1000. UI and Gameplay - I can't add details of those here, so I'll add those if you are chosen.
