This tactic explained here: t/187364/
Ahh this one. What can I say this one is going to be a bit hard to explain without some sort of diagram but I'll give it a shot. Okay so lets go over the seemingly most hated jumps by players, squares. I know with squares THE STRUGGLE IS REAL but to all those people who say "I can't do squares" maybe the problem isn't you, more likely, the problem is the way that you are looking at it.Indeed thats what i do - follow the patterns and i have big problems with squares. When you focus on the last appeared object you can just memorize everything that appeared before and make a pattern in you mind and then just follow this pattern with cursor. But if i dont follow patterns then i have to focus on next note that i'm going to press. Then how it is possible to read map? When i tried this tactic it made my play much worse. I couldnt even pass maps that are very easy for me. So what i did wrong?
Okay squares 4 notes spread out on the map that are equidistant from each other they can come in many different styles; typical squares, diamonds, rectangles (which aren't totally equidistant but you get what I mean). The biggest problem I see is people are trying to think of squares as well... squares instead of individual jumps. What I mean by that is people try to make a square with their cursor in one motion instead of 3 different jumps. It's okay squares are intimidating and even reading them the correct way can get people confused but I'll try to explain what I've found to be the best way to do squares.
With squares you want to think of them as individual jumps between notes rather than just one square. Think of it like this, a square can be broken up into 3 individual jumps (unless it's repeating in which case it can be broken up into multiple different jumps) but it still comes back down to the basic pattern. Rather than thinking of it as a square, think of it as jumping between 2 notes in 3 different intervals. What I mean by that is jump (1-2) then (2-3) then (3-4) get out of the 1 2 3 4 mindset (oh god this one's not looking so good) let me try to expand on this.
When doing a square instead of counting the notes in your head as 1,2,3,4 think of it more rhythmically in sets of 1 and 2. Count the notes 1,2 1,2. What I'm trying to say is realize that a square is merely one jump vertically one jump horizontally and then another jump vertically. When you change your way of thinking about it they should make more sense. Basically break the square up into two parts rather than taking it all in as a whole. It's a lot easier to do them if you realize that they're all movements you can easily make assuming you can probably jump up and down and left and right pretty easily by now you just have to think outside the box (pun definitely intended).
Think of it this way with any jumps you learned how to do you probably don't think of it as one motion you break it up into multiple smaller movements between the notes. I think that squares are a lot easier when you look at the follow points. The follow points give you the best way to do just about any jump but I find them to be more useful with squares. The way the follow points connect the two notes is the way you should be moving. Practice moving with the follow points that way you'll be less likely to make circles when doing squares. This may be pretty hard to follow but if I had to boil it down to one thing it would be break shapes down into individual jumps.
