As others have mentioned, some indication of what lane you're controlling would be a nice addition. Perhaps even being able to "click" a lane to switch the ducks direction. 

I really like that you took an actual game and flipped the roles, this has been one of my favorite thematic examples of that so far!

This is some real zoomer stuff! Got 30 points max :)

What an interesting take on the gamejam theme! Good job :DD

Pretty fun idea for a game. I think it would be more intuitive if you could see which duck you have selected, or just press the numbers to flip them instead of space.

I agree its an interesting concept, I did it myself haha.  I think you should select lanes with the mouse that way it's a lot faster. Maybe left click a lane and then right click to change directions.

Interesting idea, and nice execution. The controls too a while to get used to, but other than that, good game!

How about adding different-colored lines on the screen, And highlighting the selected line in a vibrant color?
