A nice take on the breakout genre indeed. I would love to see this developed with more gun/weapon types (bombs for area damage, flame thrower with fire flowing from one brick of a certain type to another, laser that would brake en entire column, etc) and maybe ammo/resources management. Like, Doom Eternal, but inside Arkanoïd.
Also, do you know of that old breakout clone : https://www.youtube.com/watch?v=SygD93F95js
