Newest release of osu! stream on platform iphone 4s.
Sometimes the circles that requires to be hit at the same time are too close to each other, such as in March Handyman (Stream+Expert) (I haven't played easy mode so I don't know if this appears in easy mode). This leads to a problem that if we tap the screen with two fingers as close to each other as the notes, the system will regard it as one tap in the middle of two fingers which leads to a miss.
I hope these notes can be streched out a little bit.

I just perfected march handyman (expert) after reading this. There wasn't a problem with notes too close to each other though, Besides, stream handles multi touching so that should'nt happen. But maybe it's because I'm playing on my iPad. Are you playing with an iPhone?
