Above Average, But Not Great
The first thing to hit the player upon loading this game up is the graphics. The graphics are simplistic and appear hand-drawn, which adds a unique sense of charm to the game, particularly in conjunction with the colors the stations give off. However it can be very difficult to find dead zones when you have 99% complete, perhaps some method of indicating where dead zones are would be helpful.
The second thing to hit the player is the music, and boy is it good. The music is perfect and beautiful; atmospheric yet engaging, and never a detriment to the game.
Gameplay is the third aspect the player encounters, and unfortunately it is the weakest. While the concept is interesting and for the most part fun, the lack of diversity or difficulty until the end is an issue, even when perfectly clearing every stage as I did. Furthermore, as I mentioned earlier, it can be very difficult to find dead zones when there is very little dead zone left, and this issue is made worse by the fact that the placement of the stations feel a little imprecise; I rarely felt that the stations appeared exactly where I had clicked. While these issues by no means ruin the game, they make what is already a rather average experience slightly worse.
Make no mistake, I enjoyed this game and would recommend it to others, but I recommend it more for its atmosphere than for its gameplay. I look forward to a better developed sequel, as there is definite promise in this game, it simply does not fulfill it.
