Things get better after the first two planets. But unfortunately the game has a huge amount of jumping and a fair amount of puzzles. I’d say the first two planets (past the tutorial train sequence) are 30% jumping puzzles, 45% exploring the level, 15% puzzling out how to manipulate the environment, and 10% combat. When you hit the third planet combat does ramp up, but it’s probably still less than 30% of the game, and there are a still a huge amount of jumping.
I’ll have to say I am pretty disappointed with the breakdown.
