If you take this game and do the pacifist route without unlocking the other forms the gameplay works wonderfully. But as soon as you get the other forms it falls apart, the spider form is buggy, the stone form is buggy, everything feels buggy, it feels like the standard way to play is the pacifist mode, which has solid gameplay and the kill everything and take their forms wasn't polished enough. Not gonna bother to try the other endings.
