I agree with a better targeting system. I think an easy patch for the English version (or both), would be to tweak the targeting system into a "flick" targeting system. This mean that the creature closest to you, once you centered the camera on them, would be targeted and then the player would have to move the mouse fast enough or "flick" the camera left or right to change targets. This would mostly eliminate the constantly changing target reticle that happens in group fights.
If possible change the ceiling limit so you could flay above the mountains, and instead make the current ceiling limit the point at which you could still land or morph back. As far as I know, that would require very little tweaking, while creating a seemingly bigger world.
Make the target reticle change colors if chest or barrel is empty or full, this way you don't have to keep your eyes in the lower right are of the screen all the time. You could also make a different color target for doors.
