I'm about 50% finished with the level designs. I've still got a tiny bit of coding left to be done.
Here's some more features found in Double Trouble:
* In-Game Message
* Switches and Triggers
* Shading
* Outside Atmosphere (Rain & NightSky)
* New Statusbar
There is also still more graphics to be done, but nothing major. There are two new screenshots posted in the image gallery
