Awesome entry! Loved the zoom in at the beginning and slowly going back to the top. Took me a minute to figure out purpurite (was searching for it on the final level lol), but then I appreciated how it made me go back and reroute things.
I had some issues with how ants choose between paths, thought that some of them were underused, but maybe that's just my perception.
Btw large ants appearing when zooming back and forth creeped me out sometimes :D
Overall, it's a great idea and great execution, also very pretty.
