Nice idea! I liked the puzzles, and the circle turning mechanic was a good idea!
It was satisfying to solve the puzzles.
I wish there were some sound effects, I also would have appreciated a way to continually move. Maybe not constant, to prevent over shooting, but maybe if I held down the button Arthur could go from tile to tile, pausing just for a second. I found tapping the buttons to be weird.
I like the little steampunk style, but I wish the background had more to it. I didn't like the blank gray background.
Also, it would be nice if
1. There was a way to remove inputs from the circle wheel during set up, instead of having to fill up all the slots and then press a button to reset it.
2. There was some sort of indicator that the level has now started.
A decent job!
