[Updated October 2 to focus on version 0.009]
Version 0.009 of the Demo was just uploaded, so you should be seeing it available as an update.
Changes in 0.009:
* Added shortcut/button (Q) for repeatedly placing the same part
* Move part buttons now have shortcut keys (arrows)
* Fixed move parts not saving correct position while vehicle is flipped
* Fixed level time stopping while in settings (could be exploited)
* Workaround for the whitescreen crash (launch with OpenGL option)
Version 0.008 changes on October 1 were:
* New buttons on build menu let you move a part (and all connected parts)
* Fix ultra-widescreen UI
* Add hitpoints to trees so they can be broken by wearing them down
* Make it possible to have green wheels
* Allow limited panning of the camera while building
* Add level time to the objectives complete screen
* Switch to show KB/gamepad controls based on input during gameplay
Note that 0.007 went September 30. It's changes were as follows:
* Parts don't get disabled by water (for now)
* First bonus objective made a little more obvious (text/popup)
* Show bonus unlock even if the objective is incomplete (shows in gray)
* Build requirements are highlighted the first time they are failed
* Show level name while building instead of The Forge
Please see the forums (Demo Feedback Thread) if you have additional requests/feedback. Will be doing another all-new stream sometime soon.
