Being 100% honest, until about the 47th ~ 48th phase, I was enjoying the game and found it quite nice, however, from this moment some serious failures began to happen, for example:
     In some phases, the girls could be reached with extreme ease, without the need to pass the course.
     The levers were useless and did not need to be activated to finish the phase.
     These two characteristics discouraged me a lot in relation to the game, but I played to the end, another thing I did not like so much was the fact that the stages do not have the level of difficulty increasing as you advance, quite the contrary, at certain times you will find very easy phases, and others of medium level (particularly, for me, none of them was really difficult).
     On the other hand, the game is quite cute, the music blends well with the stages, and it's quite intuitive, so if you just want a game to kill an hour or two, it would be a pretty reasonable option.
