Piano Tiles 2 is mostly considered as a music game, not a rhythm game by many rhythm game players. An honest advice, your fast hit from PT2, forget it. Learn how the music works, it is a slow path but gives you a better experience with music not like the whack-a-mole game.

Sorry for slow answer
In fact, FnF mods feels more like a community game to me, mostly community game only just provides a really specific kind of players. This is a general problem of every community rhythm game, although these easy charts are really quick to chart, osu! might have a better balance here…
If you are a beginner, you should buy and try some official games like DJMax, EZ2ON, blah, blah, blah which have easier charts for you to get used to the rhythm game mechanics.
