Let's say using more of the playfield could improve the map, depends on how it's doneeverything can be improved depending how it's done obv. Simplify Garven's point (correct me if i wrong): Using small part of the playfield force players to move their tablet pen/mice/big toe/potato/whatever it is in the same way often what is usually boring and even could give some people cramped feelings were mentoined by Garven what is obviously bad, but it's all depends on how mapper deal with patterns, directions of patterns, how mapper deal with spacing and billion other things you can add after "how".
In case of this map, as i've mentoined Taeyang did fine with all these things (not perfect but fine).
As for possibility of spacing increases, i believe using more of the playfield doesn't means adding more jumps, making general spacing larger, there is always possibilities to make gradual transition frome one part of the screen to other one for example.
Anyways, i think general concept should be discussed not in this thread, lol. I think it's better to back to actual map instead of having a nice chat about how the playfield could be used
i failed at simplification
