Inquiry on how GFX done on this game

Anyone knows how this visual presentation has been done in terms of light effects and animation?
For example, is it using shaders or particle effects within Unity to change colors and GFX?
Thanks in advance!

Background is parallax scrolling + light effect animation for the very back. When she hits something, a particle effect. Sliding effect is a trail renderer.

I’d expect unlit shader with light bloom. Bloom may be masked by alpha-channel or something else, for example. Additive particles in the background. No lighting necessary.

Thanks for your feedback!

I see. Thanks for your comment!
