My comments fall along the same lines as the others: Some of the lines to follow are just small enough to make it difficult.
The pros of this game are that it is cute, the music is well done, and I only found about 15% of the lines irritating.
That being said, I did find that I was unable to diffuse the bomb. I would weld the lines and one resistor would be open and the welder would continue to spark and make noises even though the "well done" had appeared. Thus I could not complete the level.
On a side note, I would suggest having Zelda's speech bubbles appear at the top of the screen instead of the side over where you have to work.
In summation, it is a cute, fun game especially considering the amount of time. Well done and keep it up.
