Wow this game is amazing, beautiful visuals, nice puzzles, really polished. The walls are a bit hard to understand, like it should be more clear that that is a wall that I can't look through. It took me a while to figure out the mirrors mechanics. I'm interested in what game engine you used, and how did you make the game playable right when I open the page, not having to press another button "Run game" like I normally would have?
