First off, the art and animation is amazing (and the colour palette feels really fitting).
As for gameplay, I love the concept, though I had some struggles on the execution. The attacks, launching, and jumping all worked well, but I immediately noticed a significant delay between two attacks, which became problematic when more enemies arrived. You can stunlock one enemy, but that doesn't stop others from hitting you in the back. When you combine the required three consecutive attacks for a launch, the short attack range, and those precious few moments after every attack where you can't do anything (not even move), it creates a situation where it seems near impossible to avoid getting clobbered.
Now, this might be just me having bad reflexes, but I can't figure out a good strategy for avoiding taking damage.
Overall, it was still a fun (if short, for me) experience, and it looks really polished.
