Good puzzles but not enough feedback in the game
The puzzles are really clever and interesting, but there isn’t a lot of feedback on whether you are doing the right thing in the game. For example, in one puzzle you turn a wheel and it causes something else to turn too, but you have no way to know that the other thing is rotating the same way as the wheel, because it is off screen. This led to a lot of situations where I would make a little progress and then get stuck and have to use a hint to work out what to do next.
