I get 'script error' in Chrome. Seems to work in Firefox.
I just played the demo in browser, and I am now a little hyped for it. A little more than before anyway.
I don't think it'd take long to learn Javascript at all, but it's another thing to do, as well as read up on the default scripts along with actually coming up with something to make as well.
After my last project flopped, I'm just lacking all motivation to work on something new.
It'd be interesting to use, but I don't feel like buying it at its current price considering how much I want it at the moment.
