I like the unique animations for each attack, and that the aimed attack is signaled by a crosshair on the player. The latter is kind of redundant since the aimed attacks are slow anyway, but it's still a nice touch. In the same vein, I like the symbols on the dynamite.
The game is not super exciting since the fight drags on for a bit and is relatively easy, but these little quality of life touches go above and beyond what is expected in terms of making the patterns easy to read, so good job on that.
