I have run short on time during the week and I was only able to check out the gameplay video, but this looks like it would be a lot of fun to play (not that I would have been too helpful with play testing probably, I appreciate watching people play but I am absolute garbage at fighting games). The characters are adorable and the art style overall is looking great, and the moves seem to be diverse and allow for some strategy (at least based off of the character featured in the video). I know how challenging hit detection and interactions can be in fighting games so I am overall very impressed with the work!
If I needed to be picky and put on my artist hat, my only note would be the animations look a little stiff for a game that relies so heavily on the expressiveness of it's characters. The primary poses are looking great, but as eventual polish there could probably be some work on the momentum on the character when she flips or rotates during the jumps, and perhaps a feeling of more weight when she lands on the ground. I will quantify that by saying these are as good or better than many of the animations I personally have done, but a friend of mine who's primary focus is 3D animation would want me to bring it up lol.
To mention the other side of the character animations, I'm very impressed with some of the lip synching on the close up shots. Lip synch can be so hard to get right and I found these very believable, the movements looked very much like the character was actually forming the words they were saying.
Overall it looks like a very good game!
