Fantastic game. Complex mechanic but not complicated. A nice simple story bot not to shallow. An obvious love letter to Castlevania SotN. Music is not amazing but good. But the graphics are *chef's kiss* It is flowing, responsive and overall a very pleasant experience.

My only complain is that the game has some stun lock, a mechanic I hate, but that's very subjective.

Plus, if you are intimidated by a metroidvania, I highly suggest this one. It's a very short game, especially for the genre, ans the difficulty is not that intense. It does rank up a bit at the end, but the enemies gives more XP and you can quickly catch up. The game gives you plenty of weapons and spells to keep up in power but you CAN grind and spend gold on items that are in between what you already have, and what you'll get, to help out.
Finally, as a Fan of the anime, this was basically a nice epilogue. Although the ending did leave me with questions, but in the best way; it still feels resolved.

PROS:
Overall solid game. Excellent visuals and animations. Solid combat with switching between wind and fire spirits a key component to avoid certain color coded damage types or to bypass enemy invulnerability. Bosses are a highlight of the game. Some seemed easy and others took a few tries to learn the patterns. Finishing the game unlocks a boss rush mode. Exploration and back tracking aren't a big focus, but doing so will sometimes get you weapons you can't buy, HP or MP upgrades, or magic spells you can't find anywhere else. Not necessary to 100% map clear or find everything in order to get powerful enough to finish the game. Backtracking is made pretty easy with generally well placed (with one or two exceptions) warp gates around the map.

CONS:
Some boss fights repeat and a couple have very similar patterns/abilities. Most regular enemies aren't very aggressive and don't pose too much of a threat until later in the game. A couple enemies in the later stages are nearly invisible or almost completely concealed making them potentially frustrating to deal with. Even though the game is short (took me 7 to finish and unlock boss rush), after 4 or 5 hours, you've seen just about everything the game will throw at you in terms of puzzles and mechanics and it started to feel like it was dragging on a bit. I don't see myself going back to get 100% map clear or play boss rush too much.
