I found my old dusty PSP and impulsively decided to replay this (apparently for the 3 time, found 2 saves from 2010).
It might be the nostalgia talking, but it surprising holds up, nothing compared to the new ones of course but it's a great hack and slash game that doesn't overstay its welcome.
It does get a bit repetitive near the end with the lack of enemy variety, but it was a fun 5 hours nonetheless.
