Wowie! This game, in my opinion, was really awesome! It expanded upon the concept of more action oriented combat introduced in the ERAM fight wonderfully! The character here is delightful, the attacks are well balanced and paced, the controls feel great, and the music is awesome! It also tickles me that the alcohol themed character is a "spirit".
Normal mode I cleared on my first try, but Hard Mode hit the right secret boss sweet spot, with me taking 19 deaths and 87 hits until I learned the boss correctly. I suppose my only gripe difficulty wise is that if you're playing more defensively, the health bars can feel kind of big, but they feel pretty well paced once you learn the attacks and play aggressively, so I think it works out. In that regard, I like the addition of the Fairy assist character if you're struggling, which does damage while you're playing defensively.
The biggest bug that I found is that if you die right after using your dash move, you get locked out of using the move permanently, until you reload the entire game. I think the timer for the dash gets interrupted when you die, and as such the state never gets reset properly. The boss can also appear flipped or glowing for a moment after respawning, but that kinda adds to the character not gonna lie.
