first, the downsides
i would like for a smoother way to rotate the objects
at first i enjoyed the space to move thing, however later i realized that it is very annoying if you have to move back and the object is in front of you
also, maybe the lasers shouldnt kill the player since it gets a bit in the way of gameplay (its probably a good mechanic but needs some work at least maybe not insta kill and reset)
now, upsides:
the puzzles themselves are fun
the theme is very fitting
and the actual laser mechanic seems very smooth
good job!
