Pretty easy game. Pro tip 1 - In survival mode focus on one glade around level 30 and it's much easier. Pro tip 2 - In vault defense save bombs for spiders. Went through only replaying a few levels to get all three stars. (I do agree that reaching level 40 in survival is harder than getting all 96 stars. However, getting all 96 stars is much more time consuming hence the hard badge vs. the medium badge.) 5/5 for the rating too!
Yes 42 is the answer to life, the universe, and everything. Read the end of chapter 27 in Hitchhiker's Guide...
"All right." said Deep Thought. "The Answer to the Great Question.
"Yes!"
"Of Life, the Universe and Everything..." said Deep Thought.
"Yes...!"
"Is... Forty-two," said Deep Thought, with infinite majesty and calm.
Just to break it down retarded style the Ultimate question = the answer to life, the universe and everything. Yet still the answer truly lies in Earth.
Aside from the glitches, (I believe most of them have been mentioned) it was a pretty fun game. Got all the Achievements except for commander in the Enforcers guild (I'm not sure why I wasn't awarded this one on the way up but for some reason it's still red). Besides the guildmaster endings there are also endings for getting 1 million gold and conquering all 100 towns. 5/5 on concept - 5/5 for art design - 2/5 on programming execution. Overall I loved the game!
