Love the concept! While I agree with most commenters, that the controls are a bit awkward, I'm a) unable to pinpoint why exactly and b) think, that's part of the game's overall charm. :) The art style is definitely far from beautiful, but I really like the use of colors. It's especially found it clever to invert enemy colors while they're in the black part to make them stick out. Would have loved some visual indicator for how far away one can place a stick. Also I found the toggling of the individual lasers once you have more than two sticks a bit unintuitive. I think the game is hard enough already, would have kept this as the simple on-off-switch it is during the first part. The idea has great potential though!
