I liked it alot! Took a little while to figure out, but almost all the instructions worked and made sense once you pay attention to everything. Once I figured it out, I couldn't stop playing!
My only complaint: I'm not sure if I'm doing something wrong for code 253, but every time I have an unplugged antenna, it seems like I have to enter 224, but when I do, I get blown up. Not sure if this is a bug or not.
