Ok thanks to my modchip I've played the demo and killed the Jaggi at least once with each of the playable characters and a few times with the long sword and have also managed to kill the bird monster with the long sword and even attempted to take on the dragon thing it calls but had my ass kicked.
My advice is to pick someone and then stick with them and if you find it too hard then maybe you should try harder as it becomes incredably easy to play after you put some time into it and start to realise how to things work and how the monster behaves, like for instance after you do enough damage to the great jaggi it may retreat back to its lair to sleep which allows you to plan a sneak attack.
Pacman taught people to run around in dark rooms munching on pills while listening to repettive techno music and for that I somewhat idolise him.
