You just need a password hack program to open your map. I'm sure one of the community members have one, but I think it would be for the best if you sent your level to them and they cracked it for you than handing out "best not distributed" programs.

To make a tile transparent, right click it in the tileset and select transparent (somewhere) in the menu. It's really short so it's not that hard to find.

To create animations, first select a row in the animation tiles window. Then ctrl + click the tiles you want to add to the animation. You can right click the animation to edit how fast the animation should go and more.
