You are correct.
For my first ever jam, I had the idea for a pixel art bear chasing after honey. After failing in my drawings I turned to inspiration from the internet. I ran into your game and started by copying your bear design almost exactly and then spent a couple of hours making edits. For this jam, I used the asset I made, modified the animations a bit, and changed the color schemes. At the time, I thought I had made significant enough changes for it not to be a copy but looking back I can definitely see how that isn't entirely the case. I'm sorry for not asking/crediting and am willing to take down the games.
