Fast progression
This game progresses really fast and in a good way. When I say progression I don’t just mean leveling up (while that is a part of it) I’m talking about getting new skills, equipment, unlocking new abilities which give their own set of skills which have a separate way of being unlocked, and better summoning. Equipment and skills go hand in hand because you need to sacrifice equipment to gain skills; this means that as you get better equipment, you will also get better skills. Then, you unlock boss stages which are used to unlock a plethora of different abilities that require a different resource. However, there’s usually at least one shared resource between stages, so you don’t have to worry about gaining skills slowly. Also, equipment summoning chances increase the more you summon. This means that as you get progress, skills will come easier and easier.
