Hey, this is a really interesting idea! I haven't seen anything quite like it this jam. I did find positioning to be frustratingly slow, and when I had to go back and forth to turn the laser on, it got a bit cumbersome. If you keep working on this, I would consider removing the on/off switch and just balancing the game to compensate!
I'd love it if you gave our game Einnsámr a look as well :) https://itch.io/jam/gmtk-2019/rate/463168?after=20#post-876146
