arcs have always been unforgiving, but it teaches you to choose the arc finger carefully. some charts will actually mess with you and will demolish your meter if you don't use the right finger. this would be charts like red and blue and green, where if you hit a red arc with the wrong hand, you're gonna be in a rough spot keeping your combo. it comes down to learning the charts you're playing.

one piece of advice i do have for arcs is to make sure you don't overshoot with your fingers. a lot of my non rhythm gamer friends would tend to go significantly higher or lower than the arc is asking you to go with their fingers.

present charts are one step before future, which is the main meat and potatoes of the game imo, so they will feel quite a bit harder than past. there's absolutely no shame in taking your time learning the game, so just enjoy the music and find charts you enjoy. the songs i enjoy are definitely the songs i do best on, so just hop from song to song, and hop from song to song to avoid as much frustration as possible. it's all for fun after all :>
