Maximo Ghosts to Glory PS2 revisiting this game test play

I had this game long ago, beat it with great difficulty 100% mastery back in October 2009, and haven't played it since. I liked the Ghosts & Goblins inspiration, was like a 3D version of the NES game that I loved to hate. Difficulty is already hard for Maximo as you progress to later stages, but made worse like many games back then by the frustrations of the camera and trying to work with that for the entirety of the game and sometimes not even being able to move it, something I never understood even back then about games how they actually made a game harder with camera buttons and look buttons, instead of keeping things focused on the back of the character. This test play, I have my keyboard set up but not quite efficiently, so will need to continue to tweak that, may have to set things up differently per choice of game. Also I don't remember what everything does in the game or even how to use the checkpoints, something I will look up, explore later. Anyway, first time playing Maximo since 17 years ago. If I give it another try I'll be starting over again, hopefully with a more intuitive setup for my controls and remembering how checkpoints work, saving, and other stuff.
