I'm not sure what you mean - do you mean stop moving if not hitting the keys? That's interesting, but we instead chose to tighten the controls a lot (after the jam) and add wind resistance. It feels much better now - will publish as soon as the jam is over. Thank you for the advice and kind words!
I had trouble explaining myself indeed, but I was hoping it worked out well ;-) Let me try it again.
It is indeed as you said. In lots of platform games you jump and then you only move horizontally in the air when you press left or right, which gives you better control over where you land. If you don't use left or right, you just drop straight down. Or, alternatively, you decrease horizontal movement speed quite quickly to make it more fluent.
In your game, you keep moving left and when you press right you instantly keep moving right. So to control where you land you have to keep pressing left and right quickly after each other to hit your intended landing spot, unless you aimed perfectly before you started jumping and there is no need to correct your course.
But, also like you said, you already addressed that issue in the not released build.
Did I make myself more clear now though? :-)
