Thanks for playing! Some of those mechanics exists for the ninja character or as upgrades. The ninja is supposed to be the character for the tetris pros with all the unique mechanics from there while the others have to rely on different tools.
Ideally you should be able to do well even if you ignore the items and skills if you're a tetris god but the enemies get really tough eventually so I can't guarantee it. There's no shame in using the items regularly, you get a lot of them.
