I kind of wish they put more effort into the game to make it more of an original title.
I feel as though Konami was on cruise control for the system, like other Japanese devs at the time who did not take its market seriously with a primarily domestic viewpoint. Until their former colleagues at Treasure totally blew their efforts out of the water and made them look bad. Konami's output after that feels kind of reactionary to Treasure somehow.
I don't know where you'd fit Rocket Knight Adventures into that equation though.
