That was a fun little game. I really liked the reflector laser and there's so much possibility for wacky puzzles.
One thing is that you don't need to move or even shoot the crates to beat any of the puzzles. Maybe something like Portal's white walls could be interesting, where only certain surfaces reflect the lasers. And while it could've been hard to know where the laser was reflecting, the wall's testing material actually helped me line the shots up; so maybe a full game would benefit from a grid pattern wall and floor material.
Overall it's a cool concept and story, with these levels leaving me wanting more puzzles (make more I beg you)
