Ants are everywhere, and I like it. It’s a fun factory-ish (I guess) game, even had some room to optimize the routes for maximum APM (ants per minute).
Looks like the font is missing some characters, such as capital letters, so I had to lick the nest.
Also, maybe being able to set routes that don’t require returning to the nest would be nice for throughput, but not sure if it contradicts your design goals.
Great job!
