It started off as an app to simulate housing in an MMORPG, since the furniture system there was atrocious. I'm now trying to adapt it as a simulator for general interior design.

Like many 3D design software, there are a bunch of tools and controls, and first-time users may feel somewhat lost. So I've made a starting tutorial to help ease users into the controls. Do you think the tutorial works well?

Let me know what else can be improved!
