Hollow knight is one of my favourite games, if not my favourite.
The fact this was developed by like 4 people is fucking insane.
THE best metroidvania I have ever played, with really tight controls, very very well designed boss battles and enemies, I can only think of a few objective flaws within this game.
HK's environmental design is wonderful: Each area feels completely unique from one another, and each has its own reason and justification for existing.
Another amazing field of design is the characters- Most characters, enemies and bosses feel lively and unique, and the silly voice acting adds a lot.
The bosses in HK are also all amazing, with, I'd say, the exception of the Pantheon 5 final boss. That one is BS. The rest are all BRILLIANT though.
please play hollow knight
