I've been playing for a year and find Dash a bit difficult to clear, am I just bad at it?

It's a bit strange that you can't beat Dash even after playing every day for a year... I suspect it's because you only play occasionally or only choose the easiest ones.

I do that often too, but I feel like my skills are regressing more and more lololol

It's amazing that you've been playing consistently for a year. Skill isn't just about time, it can also be about how you practice. Why not try not to rush and focus on mastering each section calmly?

That's normal lol I get envious when I see skilled players.
