Mobile Game

My name is Elmo Chong, Co-Founder of [login to view URL] We are a music education startup, teaching kids how to make their own music using story and mobile games. One game I would like to make is a game that is like the melody music game Deemo but with a battling element to it. The bad girls want to destroy melody (Def Tone Twins). There will be music playing and a piano interface at the bottom. The songs will be simple kids songs with Deemo like note bars coming down. The kids have to match the bars to the piano keys at the right time. The bad girls will also throw Flat Stars and Sharp Stars that the kids must destroy in order to make the girls lose power. If they aren't destroyed a wrong note is played and the player loses power. By the end of the 90 second game clock, if the player has more power the bad girls run away to a new location and say "We Will Meet Again". If the bad girls have more power, then they kidnap children you are trying to protect and take them back to their home base. Are there any unity game designers who can help me build this game?
