These are really enjoyable! I found that on the level 'four' I could do some ninja shunting of arrow-circle-blocks so that as they popped out of the conical-flask-like-structure behind me, I could move down and up or left and right very quickly to stop them entering their opposite structure. I wasn't sure if that was part of the original game's mechanics or if I was abusing the slow tickrate of puzzlescript!
It's part of the original game's mechanics, you can do the same stuff (and the tick rate is as slow, I can actually make the game twice faster in puzzlescript, but I chose it to make it work as close as possible to the original). It's usually not a great way to solve things by doing this stuff, and this is the main reason Xye has arrows that are faster than the player.
