Oops, I made a mistake in the last comment, it’s probably an engine bug and not a game bug, but I tried to do something, probably today or tomorrow I’ll release 1.4.3 :x
I really wanted to add it, but I couldn’t make it fit the game, sorry :(
(If you look at all the sprites from the game, you can see that they all have the same border of the same color and width, and I couldn’t apply such a border to this rabbit ;x)
