I really love the chaining magic concept! And really well executed too!
The boss fight is really unique and takes full advantage of the mechanic presented.
trying to chain attack while dodging bullets and can take a bit to get used to.
But I personally don't have much problem, I usually only focus my eye on the character to dodge bullets and just swing my mouse around.
I few issues I have bit it may just be me.
I personally think the energies you are supposed to pick up are too hard to see.
and the background of the stage 2 burn my eye. (I hate light mode)
But overall the game is great!
