I have today released version 1.3 which adds the option to skip the last cutscene and a gallery option, note though that the cheats in question only add the possibility that you can see if an agent is going to cause a transformation or not. However the new gallery mode might be what you are looking for. If you would just like to play around with the transformations you can click 3 times in the bottom left corner of the main menu screens and that will fully unlock everything in the game, including the special game mode and all transformation options in the gallery.
