Thanks for playing! I did an post here earlier about that, we used that pre existing art as placeholder while developing, and I thought would be nice to keep it since it was already working (a little extra content would not harm), I did not saw that option until there was no time left to take it out from the game, and didn't think was fair to my partner who did all the art if we said we didn't make the art because of it. Anyway in a post jam update it will problably be replaced to a created sprite! (I also wanted to in overall make the animations a little faster after jam)
