Thumb hero Reaction game.

Previously created game, I want remaking in unity, game artwork already created, looking for someone to recreate the idea. Reaction based game.
The game will consist of 2 live leaderboards.1 leaderboard will be for general gameplay. The second leaderboard will be for competitive gaming. In competitive mode the player will have a chance to win prizes.
Gameplay
The game is a reaction based game where the white line will grow and shrink in length.
Player must stop the line in the red box.
Each level passed, the player will receive coins and stars (starts will be used to start a game) each level will be slightly harder by increasing the line movement speed, the path the line takes and visual distractions

If interested I can send docs with the complete ideas
