Hi Fabian. Glad you liked it!
Thank you for your feedback. We are considering how can we make the game flow a bit smoother (tweaking the waiting times and trophies), but you're right, we intended to leave that time for cleaning the trophies in the first place :)
We use a demi-random algorithm to pick the sentences, so it’s possible one may appear twice, I wish we had more time to make more requests so this wouldn’t happen so often...
