We were inspired by it. So it's the same graphic element that's used for the card. We weren't trying to copy it at all, but our idea corresponded pretty well to last year's visual, and it saved us time fetching a resource we already knew. We did try to find another one, but it just works too well.
And for sound, the assets are different. But I suppose that since the objective was quite similar, I unconsciously made a result that almost looked like a copy.
Thanks for the feedback, I'll be looking for more diversity in future jams, that's the point of a game jam after all.
I hope you enjoyed the game ^^.
