This game is pretty sweet. It's calming and relaxing. People don't see it for that; its too hard for them because they don't focus. 5/5. I love Perfect Balance.
In short terms: try exiting the browser, load the internet back up and go back to BoomsticK. Perhaps it will show that you've won it. I don't know if it will work for you, but I did this and I got it. If you can, please comment again of the results.
Okay. This is how I got the ticket. After winning the challenge and the first two achievements in game, I noticed that I hadn't won my ticket but it said that I did get it. So, after seeing that what people have been saying is true, I got out of the browser, reloaded the BoomsticK game again and suddenly it said that I had won the ticket. I checked again and YES. I won it.
I didn't mind it actually. Although some may reckon the gameplay is flawed, I believe the concept of it is great. I wouldn't be able to do any better :P 3/5 for gameplay, 5/5 for idea.
