Neat game, love the visuals on this one. It's not very clear what I have to do and how I have to do it, I think it lacked a sort of tutorial level to teach the player the mechanics, then I guessed the idea was to get the balls into the basket, but then as soonest one gets in I get popup saying "Game Over" but I can go to the next level, so did I lose or win? I don't really understand.
The small slopes are broken and I am unable to place them or letting them go, they get stuck following the cursor, I am still able of grabbing the other pieces and placing them but the small slopes remain there.
Also, idk if this was intended or not but I can push the balls with the pieces when I drag them, but I think you should get rid of that and let the main focus be getting the balls into the basket by using the pieces to lead them there, not by pushing them while dragging it.
