Pretty good start, and waiting for the full experience.
There are some things that could be better. First, why does the combo prompt jump between being above the enemy and above the player, this is more annoying than it is challenging. Second, is there a reason why you would even use the Knife set (with the pre-set skill chain) over the Grimoire set? Grimoire set is way more powerful than the Knife set due to having access to stronger spells AND an automatic damage buff.
If we could see the Skill Chain having good uses from the start, I think it'd be a big hook. What I'm currently hooked by is the story. I want to see how it continues and ends, so I'm hoping I see a full version one day.
I made a small presentation of this game here!
