Lol, you still have 1.21.

Update to 1.23. It fixes some bugs. Then get jj2+. It fixes even more bugs and adds a ton of new features, and you can get to play some really cool levels (which I'm more interested in seeing others play)! You should be able to find the plus download easily, though here's the link to download 1.23 which you'll need first:

The LPs are long so I'll watch them later sometime.
