I like the creativity of the idea of a plane, but I sort off wish the looping was incorporated moreso into the game, like maybe getting points for looping enemies. But I gotta ask, how did you make the thumbnail image? It just looks like AI art to me, and it's not a Kenny asset like you listed. I would really recommend changing it, even if to one of your screenshots, as AI art is against jam rules. I'm one of those people who don't like AI art, so as a solution if you really don't want to make art (or look for it) I even made you this thumbnail you can use!:
It didn't turn out that great, but in my book anything's better than AI. I hope you consider it! :)
