I have the feeling that most people love this game, because they decided to - I for once do think its "lame", as someone put it, when the sequel contains at least 3 puzzles that are similar or even the same as the first game. Especially with all the deliberated suggestions and ideas from this community the sequel could have had so much more depth.

You should not automatically asume that everyone being far ahead does the time-travel cheat. You forgot the beta testers from bigfish, for example.
