Hello,
I really like this version of mahjong you've got here. Good stuff.
However, in chinese cartoons there's a common thing when charactars call tiles, they throw them on the table and swish them over into the side of the table.
If you try to do this in this mod, the tiles just go flying off the table. No good!

I added some hidden walls to the bottom right area of every player so the tiles fly into something, and it seems to work. It'd be neat if you could add this to the main version as well.

edit: forgot to mention, I took the invisible wall thing from here
