The perspective used feels quite unique, and the HTML version actually worked perfectly for me as far as I could tell 👍.
Something a bit tricky was trying to figure what I was supposed to do, I thought okay, maybe I'm the square, and I tried pressing the arrow keys, I then read the description and realized I had to use the mouse, but still didn't get how to move the square, eventually I moved a gear and was like oohhh, lol.
Locking the gears in place could be good, but I think it might be more interesting if you find a way to make the gears moving around like that a feature, it was kinda funny they kept popping out of place, making me have to rush to get to the next set of gears.
I look forwards to seeing if this gets improved upon, and get some more levels in the future, cheers!
