While going through the known bug list, I fixed a bug where the game freezes indefinitely when going to the Play Custom Puzzle menu. I also fixed some problems with how the editor auto-numbers objects and some quirkyness with the transform pane updating when it should not.
I'm still trying to duplicate and fix some crashes. If you have experienced any, please e-mail me at firstname.lastname@example.org and I'll try to pin down the bugs with your help.
You can either download the update from Dominoze.com or run the Update program that came with the Dominoze Demo.
