Haha thank you very much for the video! Was fun to watch, and your feedback does matter - as this is my first game I try to take in any and all feedback, and will probably put it to good use in chapter 2. Unfortunately as there are SO many people it's hard to strike a balance, and eventually some people will find it too easy and some too hard!
I hope you had more fun than frustration though :)
There's nothing after level 10 - at the moment! The messages are just references to the games these paintings are of, and the ! to ?... is me hoping I'll get to do chapter 2 :)
