I really liked the character art(both in game and during the dialogue)and overall look of the game! The character animation was nice too. Another thing I really enjoyed was the music in the level, really had a great anime vibe to it!
The combat could have used a little more feedback/juice. Currently hits don't feel very satisfying, and tossing the enemies into the air with any hit makes combo-ing them difficult. I also encountered a few bugs... if I tried to play again after game over, the intro dialogue would not proceed... I had to refresh the page. Falling off the screen at the start doesn't lead to game over either. I think I reached the end of the level, but I didn't find anything there. I imagine that this was due running out of time in the jam, but maybe I missed something.
Still, I think you did a lot of great work on this! It's a great start, and I hope you keep working on it!
