>>349The OSTs are pretty great, Green-Eyed Jealousy is one of my favorites, I use Deep Mountain as my ringtone. However, arranges vary so much in quality its rather frustrating, found a few good ones though.
As for the game, I was absolutely shit at them at first having difficulty with anything past stage 4 on normal difficulty, usually through...well reflex training that is easy to lose if you don't maintain it, and pattern memorization, it can get less difficult.
As proof, I used to be able to beat EoSD extra stage, but now I can't even get through Undertale without dying once and that is literally babby tier compared to 2hu
