You need waterfox browser and clean flash to be able to do this method of the train glitch. It is by far the best recreation of the original flash on chrome experience and way less laggy than flashpoint.

You spam right-click and move your mouse very slightly so the character moves and then you just go through it. It takes a bit of practice to be able to do it regularly. It is a little slower than the old way but it's still faster than not doing anything
I just wanted to say that I made Drakens värld a Twitch category. https://www.twitch.tv/directory/game/Drakens%20V%C3%A4rld
I have no idea how this happened and I was just practicing a and chatting with my friend and I did not think this would happen. I don't know how I did it or how to recreate it. I have heard of it happening with the third level but not the second.
