It took me about 2 hours and 30 minutes to complete the game.
The boss battles were interesting in the way all the bosses attacked and their gimmicks!
The action elements along the way were very difficult. The controls for switching between the three characters were very confusing, plus the mage had to switch magic as well, which was quite difficult.
I almost gave up during the game, but I felt a sense of accomplishment every time I cleared a stage that required quick operations, and I was very happy when I cleared the game.
