I did not enjoy the game personally, It progresses too slowly and after awhile my finger does not enjoy the holding of the arrow key.
The game was beautiful though, the music was great an the art was wonderful 3/5 due to painful finger afterwards.
Would be a great thing to have a better training option after the second, Takes forever atm.
Otherwise this game is amazing, it's not too frustratingly hard but it's enjoyably difficult.
