I know the feeling of “these games should exist” and then the disapointment of them just not existing.
I remember back in the super smash bros brawls days wondering why there were no good smash clones and nowadays we have several, so don’t lose hope. The day of the PS2 style platformer renaissance may yet come!
Speaking on PS2 though have you ever heard of/played Alien Echo? Its more of a hack and slash than a platformer but it does have shooting and its a lot of fun. Cheap too, I got my copy at a local store for $10.
