I somehow missed Fell Seal: Arbiter's Mark. It looks interesting and I may give it a go.
It's great. Easily second best this year. The class system and combat and are very enjoyable, and the story is serviceable enough to keep going.
Indeed, it is pretty good.
Its biggest downside is that on one hand it gives you so many classes to try out (and combine) - but on the other hand punishes you severely for actually doing so.
Having a larger number of characters (one for each class or combo you wanna try) that regularly rotate means most of your characters will be behind on XP and levels, forcing you to grind to keep advancing in the story.
You could recruit new characters at a higher level, but their class levels (which are separate) are extremely low - a lvl 5 character with a lvl 9 class will be much better than a lvl 9 character with a lvl 5 class.
Best would be to just pick your 6-7 characters and stick to them - but at the beginning, you don't have most of the classes so you don't even know who to stick with.
