You're right - fixed. =)
I chose to include only a tutorial screen because I personally prefer exploring games instead of having everything explained step by step (and most players skip tutorials anyway.) There are some features that could have been shown in more detail, but we simply didn’t have enough time for that.
And yes - you're right again - it’s a game jam project. We’re already happy if people even play it; we don’t expect anyone to spend hours on it - but we’d definitely feel honored if they did. =) And I’m happy that you wanted more content :P It would be nice to improve the game further and make it more fun for you. =)
