2D Android Games : Flappy Bird Like

I'm looking to develop a "Flappy Bird like" game. Instead of Flappy, it is Trampy, a tramp guy. Trampy is a tramp (he look like Mario). He's the main character. Its goal is to pick up a maximum of yellow coins (the amount of coins is the FINAL SCORE) by using raised platforms (wall) in a city setting. He can met "wall" and "hippies" which are the only obstacles. Yellow coins are variously place between or over walls. Every 3 seconds Trampy met a yellow coins. Instead of pipe in Flappy Bird, in this game Trampy progress by using wall. The wall are like cloud in the sky and are variously place (lower or upper). Trampy can fall from the wall, or crash his head/body from a wall with a bloody disgust animation. Trampy must be really hard to manipulate, a high score must be really difficult to have, the game should make people becomes mad but makes them laugh about that crazyness. Trampy can pick up alcohol bottles on its way and hallucinogenic mushrooms which are special extra. Trampy can met those extra every 10 to 20 seconds Trampy can't have more than 1 item at a time. (One or the other). When Trampy use hallucinogenic mushrooms the speed of the game started to changed (slighty lower) and the manipulation and precision of Trampy becomes much easier for 5 seconds. (The user must tap on the screen 2 times in order to use it) When Trampy use alcohol bottle, it is showing him drinking the bottle (0,5sec animation) then he's become immune from hippies. If he met one he'll kick it off from its way automaticaly and the immunity taked end. (The user must tap on the screen 2 times in order to use the bottle as well). Manipulation : The progress in the environment is automatic. When the user met a "wall" or a "hippie" he must tap 1 time on the screen in order to avoid it and 2 times to use an item. How does trampy can die ? : -by falling from the raised platform -by crashing his head/body from a wall. -by being kicked by hippies.
