I had issues with the first game, enough to put it into the "not recommended" category, but was still able to put up with it enough to play the puzzles. The same cannot be said of the second game, which is readily apparent as being far inferior in quality. If a good game were equivalent to Ghostbusters, the first game was Batman Forever -- not good, but with enough redeeming values to be enjoyed. Puzzler World 2, however, is more on the level of Manos: The Hands of Fate; on several levels it doesn't just fall short of its goals, it fails to even be recognizable as making a worthwhile attempt.
The issues of the first game not only remain, they are exacerbated. The "picture quiz" game, which has absolutely no business being in a puzzle publication on account of not being a puzzle (memorizing isn't problem solving), remains, as does the kindergarten-level Silhouette. Codeword, one of the more creative and intelligent games of the original, is removed. Hangman is still set at a level that is too easy for anybody who can read at a first grade level. The maximum number of wrong guesses one should be able to get in Hangman is 6, a quarter of the alphabet. PW2 allows eleven wrong guesses. Another irritation from the first game, that being crossword answers that have multiple viable spellings not being accepted (and not being blocked because it doesn't completely interlink the way a proper crossword should) also continues here... along with some clues just being wrong, at least by American definitions. ("Mooch" does not mean "skulk"; it means "freeload".)
Still, issues of the puzzles' difficulty levels would be minor complaints on their own. What sinks this from a C average all the way to an uncontested F is the interface. There are numerous design changes in this version that are just baffling. The "hint token" prize boxes of the first game -- mildly annoying on their own -- are replaced by a "Wheel of Fortune" spinner, complete with requirement that you spin it with sufficient speed (remember, this is a puzzle game, not a skill game). The Fitword puzzle now requires that the words be manually dragged into their places rather than typed. The "Sum Up" puzzle has the answers floating around aimlessly for no reason other than to make it harder to see what you're trying to click on; the actual problem solving isn't made any more difficult, it's just the physical aspect that's made irritating. The crossword puzzles skip over filled in letters while you're typing -- so for example, if you already have the "N" in from another word, you can't type "ORANGE", you have to type "ORAGE". Worst of all, the Link-A-Pix puzzles, the most fun game from the original, are rendered completely unplayable by a decision to require the user to scroll around the screen instead of showing the full puzzle.
As if these bad design decisions weren't enough, the game is also severely buggy. There's visible lag in response times, items don't always line up the way they should (the word search lines are often off-center), and worst of all, a lot of it just doesn't work. Scrolling in Challenge Mode can't be done with the mouse, but only with the keyboard. The scrolling in Master Mode and the Trophy Room don't even work with that. There are arrows there, but you can't click on them, you can't spin the mouse wheel, and you can't use the arrow keys. You're told there's stuff to scroll to, but you can't scroll to it. And to top it all off, there doesn't appear to be a "QUIT" button for the program. I had to use Task Manager to shut this piece of crap down. I won't be starting it up again.
