Thank you so much for you kind words!
The artist will be very happy to hear your praise over their work, I'm very proud of them!
We tried our very best to get it working smoothly on web (got down to 200 batches) but I guess it still needed some more work :D
I did consider a flag for repeat users but between time constraints and trying to figure where I'd put the option to let users repeat the tutorial if they wanted I decided against it. If we took this further we'd definitely add that sort of thing :)
