Cool game, it's a pity that there are few ratings, but the puzzle are cool.
When the theme of the jam was announced, I also wanted to do something similar with a mirror and so that only the character was reflected in it. But he did not, because the restriction interfered with "Windows as mechanic."
The implementation is worthy of respect, only there were bugs with boxes, but since there was little time, it's forgivable. Great job! You are wonderful.
