Also the minigame is unstable. Many, many times I played and moving at relatively low speed (less than 40% of the maximum), then the game stops and tells me I failed. Assuming it uses Monobehaviour, I think the game checks the position your mouse travelled since its last Update() without considering the elapsed time (Time.deltatime). If your computer stutters a little the game fails.
The game should probably not end as soon as the player moves too fast anyway. Give us at least half a second to correct our speed.
There are a lot of other things that can be improved but the game has great potential. Keep it up
