This had a very strong impact! The introduction was super strong, voice acting was well done and the effects on it really enhanced the vibe. The arena and character designs were super cool and the music really fit well. I think with a bit more work on the fight itself it would be really good! I think adding some feedback to the other moves would help a lot, too. I tried them out a couple of times and couldn't tell what they were supposed to do, though after I would get hit it would look like I didn't lose HP, so I assume they did do something. There was also a moment during the mid-combat cutscene where I got attacked in the middle of the dialog (since I assume it recognized it as her turn while it was playing still). I didn't lose any HP from it, so it wasn't the biggest deal, but it did throw me off from the scene. Also, it looked like if you hover over the buttons during cutscenes, you can see the tooltip for the attack hotkeys.
Looking forward to seeing where you take this!
