Swiping down can sometimes accidentally move the piece sideways

[Tomin1]

Asked on harbour: "Swiping down can sometimes accidentally move the piece sideways which is very annoying. Hope there will be a fix."

This is a bit more complicated issue than it may seem on the surface. Limiting movement in horizontal direction can make the game feel uncontrollable in some situations and we should definitely avoid that, but I mostly agree that it's a little too easy to move the piece sideways when trying to drop it down. I think this should be prototyped a bit before deciding what will be the fix.

Feel free to suggest possible improvements to fix this below.

I wonder if it would work that when the piece is moved in vertical direction (y-direction) it would increase resistance in horizontal direction (x-direction). I think the same could apply to the other direction too so that when one is moving the block sideways it wouldn't move vertically so easily. If we increase the resistance gradually, then long drops are more unlikely to move the block sideways but it doesn't become too difficult when moving the block just a little. That could be implemented by having separate dynamic values for blockSize in x and y directions and we'd just adjust those when the block moves due to a mouse event.

Anyway this is exactly the kind of idea that will need some experimentation.
