hey, thanks for the comment.
it should only take 9 iterations to get through the gate, unless there's a glitch. the optimal strategy is to go back and forth between exactly two tiles, i'm not sure if it's possible if you use any more than that.
i didn't realize this until playtesting just now, but it is a little difficult depending on the way you're doing the inputs. however, with the keyboard controls it is, in my opinion, not too difficult, as you can mostly rock your finger back and forth between W and S. note that you do not have to time it correctly--as long as you're holding the key down it will work. it is admittedly harder with mouse controls which is my bad. i got very used to the necessary action on the mouse while working on the game. you can still do a somewhat similar technique of "buffering" the input but it is probably not as easy as with the keyboard.
i'm not sure what you're referring to by your comment "already would be a terrible idea." if you want to clarify feel free.
