The game's really great. I really wished they would give us a level editor of some kind so we can make our own challenges and share them with the community.
Personally, I have done the game, and i find it extremely irritating that you can't simply unlock the other challenges by completing the earlier ones, but rather, wasting your time finding clue in the game! Why? I just want to play the challenges!
Any kind of INI trick avail for that? Trainers seem to only give the usual "infinite this-that" crap. I just wish to have all the challenges available.
