I love the art style in this game, and the advancement of the puzzle complexity was great.
I would like it if after the first couple levels your player "earned" the ability to see the numeric angle they were setting things to (or there were art changes when at specific angles, like 45' or 60') because it was a little laborious to walk back and forth between laser and mirror to make minute changes... The walk back and forth is ok for the first couple levels, but it might be a nice quality-of-life to earn that visual feedback later in the game.
