I have some issues with the latest version of the game.
First of all, when I re-downloaded it and started to play again, I found that none of the keys that I had previously set did anything... in fact, no keys did anything, period. I figured out to open the Keyboard Settings open and started fiddling with that.
I went to set the arrow keys and found that when I tried to set the Move East option to the east arrow key, it gives me the message "no east" and refuses to let me set it to the east arrow key.
I also found it rather annoying that the key assignment popup would disappear behind the Keyboard Settings window if I accidentally clicked on the larger window instead. Would it be possible for these to both work from the same window to avoid this problem? I don't remember, but you might also be able to lock the Keyboard Settings window while the key selection is in progress to prevent this as well. In fact, you should lock the whole game window while in this editor, because I accidentally started my game while fiddling with the controls.
Also, the escape key should cancel the key selection. At least, that's what I'd expect it to do.
The controls started working again only after I finished up in the Keyboard Settings window. They should have worked as soon as I started the game. And I still can't set the East arrow key properly.
