I was intrigued when it first came out, but was hesitant even when it went on sale because while it still looked interesting I wasn’t sure I would enjoy it.
But I picked it up during the sale and while it is challenging, I found it to be quite fun, after figuring out what I was supposed to do; there’s not really very much instruction, but I suppose that kind of adds to the early-80s-Eastern-Bloc atmosphere of the game. It certainly helps if you already think inspecting and comparing minute details is fun (which I do; I’m weird like that).
