Definitely made in GMS2.3, so I'm not sure what would suggest otherwise? It's definitely still rough around the edges and doesn't give a clear objective. Thanks for playing and I appreciate the feedback!
Ah, no worries! As it turns out, it's a spinoff of my first gamemaker game. I tore down the original to a few sprites and took it in a new direction for the jam. I suppose the icons/splash carried over from the old project files, but I didn't think about it since I normally build for Android.
