I appreciate the detailed response to some of the issues you had with the game. I was given this sort of feedback as well in regards to the color skill issue. I will admit that this was made with an in-medias res in mind and that might be a factor for the confusion. Its an intentional confusion, but it could be immersion breaking to some. I intend to answer a lot of the "Chapter 5" questions in the continuation of this entry series under a different name.
I was shorthanded with the testing, so I wasn't sure how the elemental immunities could detract from the experience. And I will admit I was trying to emphasize the use of Kuronigozo because if the enemies have no immunities, the player would be wholly relying on Tanumaki without using Kuronigozo at all. Though I can see how this could be a negative. This is good player feedback, I'll keep this in mind.
I also didn't have time to add an analysis type skill, something the previous game was a lot more clearer on.
Once again, thank you for taking the time to play this.
