Thanks!
Even with the low scope i set myself, there was a lot to do and i was aiming for the simplest thing possible because this was also my first game ever. I definitely agree that better music and adding sfx would make the experience better.
About the game design choice. I honestly was out of ideas how to make the fox catch up to the rabbit. The game evolved out of a totally different idea and things just came together like a puzzle. The rabbit copying your movements was the only thing left to resemble the theme of duality. But your idea actually sounds like the simplest idea that i didn't think of... Would need to try it out and see how it plays out that way.
Also i'm glad to hear that you enjoyed the level design. I was afraid that i wouldn't have any levels at all as i quickly did them the last few hours of the jam, but i really concentrated on making you have to choose between a few paths, possibly backtracking and trying my best to not have a level where you just get stuck and have to reset the level as that frustrated me the most.
Thank you for your feedback and thank you for playing! This game jam has been a blast.
