Art is good except chibi part which is very annoying style because of how less info it gives about charecters to the viewer.
So why show is bad (contains small amount of spoiler),
humans with cyborg bodies act like too childish and except MC. Cyborgs don't act like human at all.
World building has a lot of flaws, its dystopian with mass surveillance, but time to time that surveillance became useless in most critical places like debugging center.
Also viewer needs more info about how all the humanity being okay with playing deca dence as their only hobby and job. As i said cyborgs in show supposed to be human and they are far away from being a human with their motivations, actions and desires.
