Really slow loading... (unless it's just my computer at this moment).
Ahh, forget it! After 10 minutes, it's not even a quarter of the way loaded!

I had this issue first, but then refreshed the page, and it suddenly loaded very fast.

But I was too slow to get through all levels within 1 minute, even after 3 tries

Thanks Mistery

What was that full black screen (#17, maybe) ? Was there really a square in there ? If so, I got real lucky
