Things I liked: This has a lot of potential and it is very well made. I would love it if I could understand what to do lol. The graphics were also really nice.
Things I disliked: The music is ok but it is too short and it repeats too quickly. The X on the corner of the items is supposed to delete them? Because it isn't working for me.
A visual tutorial may make the game too easy for people who know about the subject, but for most of us it is a necessity. I have no idea about electromagnetic devices so I got stuck at the first level. Then I read your reply to Ashkman and I understood what to do, but then I got stuck again in the second level XD
Also... I didn't understand how it fits the theme :P
