Fun game. Being absolutely atrocious at WASD meant I couldn't do much, but I could easily see the concept and how the game was supposed to work. Good job!

For a jam, arrow keys might have helped, just because trying to control the beam while also using the key to switch which size was operating was difficult. I completely understand control issues as this kind of thing probably needed a gamepad joystick to really use well, but not everyone will have that readily available while trying out jam games.
