Only giving a no commentary video with no explanations or actual "tips" to pass the levels and call that a "guide" is straight up lazy.
Some of the Hard Levels are straight up bullshit, well, at least one of them could be "cheesed" but still it depends a LOT on luck, you just put bullet sponges alongside with the bosses and that's it, there's your Hard mode. It's not even funny and just for the same animation with three different speed up levels it's not even worth it, Level 7 is awful and unfair and also there's a bug in the gallery where you can't even unlock the K.O Base scene at all, even if you try every way that's supposed to unlock it.
What a waste
