Many thanks for playing !
Well, you are right.
The hardest game is the first one, because it's both the one that ask constant concentration and the one of the only two we can die in. I though of making it the first game for 2 reason. First, action is "cool" and player would be more gripped with continuing the game. Second, since the first game is the one we play the most, I though it would be easier to handle with later easier games.
But hey, maybe your thinking is better, I don't know ^-^
