I agree with most people. The first half of the game is as wonderful as the first Puzzle Agent, with its eerie atmosphere, characters and events (I especially liked
the whole part with the Astronaut leaving a message, the search for missing persons, the entrance of Korka... Olav's cabin was very good too), but the second half feels rushed and with too many answers in too little time. Also, the answers weren't that good - too much cliché as someone already pointed out - I admit I lost my interest when
the whole tower of the first game crashed down, with the hidden people being good, the brotherhood being good, the astronaut being a real astronaut....
The puzzles were too simple or too strange, poor puzzle design imho, as rushed as the story ending - even though some good ones were present I must admit.
All in all I still love its atmosphere, music and artsy graphics, and some of the new story ideas, but the first Puzzle Agent probably took me to expect too much

this one is decent but not wonderful as PA.
I don't know what to expect from Bermuda also, I think Scoggins was a great setting.
I regret not being able to play a full series.
