Not Worth A Download

Everything good that they advertised, you have to pay for. Everything that you don't have to pay for is difficult to navigate and use. You can't even make a parallelogram! Trying to do anything makes something else happen, and the 'help' menu is not useful and a mess. None of the "features" they showed off were available for use. The settings were difficult to understand.
Overall, it had a feeling of sloppiness and incompletion.

It's bad

Seriously, you do not want to try it.
