If you want to play a game that involves reading instructions and learning to read/execute them quickly, this is actually a good game. I won all the difficulties at least once within an hour, so it's not that hard.
My only issue is that Easy is actually pretty hard because some instructions can be completed in a few seconds while others can take a minute or more, especially on your first few tries.
Pro tips:
1. I used four tabs to look at the instructions on a separate webpage next to the game:
-bomb diagram (shows you what part of the bomb is what, worth looking at closely)*
-bomb/fuse panel serial numbers.
-First page of 'Instructions By Code'.
-The other, higher code number instructions. This I do the most scrolling around in.
*On easy, the name of bomb components shows when you hover over them with the mouse.
2. By "don't pull/plug-in the antenna when the LED is lit," it means wait until the white light turns off (it blinks slowly), then yank it out/push it in.
3. It takes perseverance to know the bomb well enough to defuse it correctly and quickly, same can go for effectively reading the instructions, so keep trying if you're in it to win it.
