Great work on the cutscenes and the lovely 3d models!
Very interesting battle system! It definitely needs some kind of tutorial to explain the player has to perform an input at the right timing! I couldn't figure out how to do a multiple combo though, if that's possible.
The story looks like it could be interesting. It's too bad it's only a very short prologue.
I found a possible bug: The EP bar (EXP?) stays at 100% after leveling up to level 2. In the character stats screen I can see the EXP is still going up after each battle, though. I kept going until level 3 and it still showed as 100%.
Looking forward to see what you can do with your project after the jam!
Edit: I just noticed you also included a Japanese translation of the UI and the dialogues. Very cool!
