I'm actually confused (and now intrigued) by this... (And I'm also a showman). But I really have no idea what you are talking about, and would really appreciated a clarification.
As an statement I will say: I DON'T HAVE UxL IMAGES IN MY GAME... AT ALL. And I know that first because I started this game from scratch and second because I just checked... yes, I had to check, that how confursed you got me.
At this point I don't know if you are talking about actual pictures (for scenes and such) or sprites and/or tiles (But I bet these last one are the culprits).
But I don't use pictures of that game in mine, the sprites are totally different and I even use a different resource for that.
And the tiles, well, tiles sets are used by a lot of different developers for a ton of games, so there is the possibility that the two games use a couple of the same ones.
EDIT: Indeed the two game use a couple of tiles from the "celiana tile pack". And you will find other games using those, those were NOT made but Wootch.
So, it was all fake news.
