Fantastic idea but I would love to be able to import my own .stl, .STEP and other file type of models I have made to then test in-app.

The game is nice but for me you should add to the tutorial something like a skip button for those who don't want to do it and then later like the workshop where you put your creations and download the creations of others and then you can import models like cars or planes to test the aerodynamics....

should be able to move the wind/smoke
