The art is absolutely the selling point for this game! The maps and HUD are kept simple so that the face graphics of the characters can shine. The contrast between the super detailed face images and the almost flat-feeling battlers / sprites was a little jarring, but considering how long art takes, I imagine that was likely a jam time constraint thing more than anything.
The narrative is well-contained within this experience, even despite the name being "To Be Continued" (and after playing, the title's link to the story -- and the theme of the IGMC -- is obvious). The humor and the super meta nature of the story are not for me, personally, and because of that, I had a hard time engaging with it, but it was competently written, and I can see why others who prefer this type of thing would really love it.
I will say that the hardest thing for me to grapple with was differentiating between the characters, outside of Neli. To me, they all came off as too similar in personality, always antagonizing each other and just generally being one big cranky conglomerate. If it was just one character with that sort of personality, I think it would have a better overall effect and allow each of the characters to shine through and find a unique personality outside of the general snarkiness that blends them all together.
The battles were well balanced, and I liked the animations / action sequencing within the battles! I also enjoyed the different battle music that was used throughout. Since so much of the game is spent in the battles, having unique themes was a really good idea to keep the battles from all blending together.
Congrats to you and your team for putting out a well-packaged, completed experience and good luck with IGMC! :)
