Game Similar to Flappy Bird

Game designer and developer for game similar to flappy bird with added bonuses that allows user to collect coins and use them for items on their next round that will help them get an advantage to advance further. Also need a world leaderbroad based on points and distance. This game should be completely unwinable and will get harder as distance grows. Mechancis should be similar to the game flappy bird but not a full on replica. IOS and Android app required. Would like to intergrate some Web3 elements and make this a blockchain based game...provide your input with quote
