Absolutely! One of those deceptively simple games that let you fool yourself for the first couple of levels into thinking you know what's going on :) I gotta get it off my system at work or it'll cost me my job! My son, who loves solving logical puzzles, has a blast with it. Thanks Brutal Deluxe! John P.S. Cogito was the first file I managed to pull off of a binaries post. T'was an interesting experience!
