At the start, there are buttons to click and some instructions on how to play. It wasn't clear that you actually have to press one of the buttons to bring your character into being. Everything else was a click, but that was a button press. Once I figured it out, it was fine, but why would I have to figure it out? Why wasn't my character on the screen from the outset?
When the game started, I didn't notice that the P button did anything, it was only the E button that had an effect. Was I missing something?
