This game is pretty amazing. I really liked the strategic aspect to it.
What I liked:
1. Absolutely beautiful visuals
2. Music and sound effects are very polished
3. The gameplay was challenging, but didn't feel unfair
4. The emphasis on the combo meter to be able to beat more powerful enemies was well implemented
What I didn't like:
1. While the art style was gorgeous to look at, the enemies' colors felt a bit off, and a bit out of place with the rest of the palette
Other things and suggestions:
1. I think the way the game implemented the theme more wasn't the combo meter itself, but rather, the combination of attacks that the player selects to match those of their current enemy.
To be fair, I'm having a hard time finding criticism for this game, and I know my dislike point is more of a nitpick, but that usually means that you did a very good job making this game.
Great work, keep it up
