I'm glad you enjoyed it! :)
It does tell you in the tutorial dialogue that you have to hover over the wordbox and press spacebar, but I forgot to highlight any of the words in that sentence so it makes sense that you missed it. It does make it seem like the information isn't important.
Being able to skip the dialogue is a good point. I'll probably add a "skip tutorial" button and the option to skip a dialogue line before it's been completely written out.
Randomising the pitch is also a good tip. I'll make sure to fix that once the ratings are done and editing is enabled again.
