And so, it is simply that, fall onto it, even the wooden rigid ring part, and as long as it spins up before you technically hit it, you get away safely. But if someone happens to pass ahead of you, and it's not quite prepared for you you could just go splat... hmm k.. i can live with that, Kudos!

Well we originally were setting up the bottom portal further away from the tower and running into it (which worked) cause we thought you needed to go through the portal. But then trying just a straight drop cause sometimes it looked like we hit the top and it worked. So after setting up a straight drop aka no keyboard required, we basically hit the top of the portal and it still counted as going through portal. It seems the hitbox for the portal goes up a bit further than one would think.

Not sure about if there's a second player going by at the same time would stuff things up, I don't think that would matter as one can usually head through portals simaltaneously as another player, I would have loved to show the video but seemed like too much effort to post lol
