I thing it’s important to decide whether it is a clicker game, or an idle game. Because for idle game you want to move away from manual gathering pretty quickly and instead rely on automation. And clicker games, well, they are bad for my mouse so I don’t like them.
There is a lot of potential for an interesting idle game. But the balancing needs some more thought. Remember that this is a jam game and people are unlikely to spent more that 5 minutes on it. So given that, you can calculate how fast the progression should go to showcase all the interesting things in 5 minutes.
Other then that, I would probably suggest switching the font for a more readable one, because you have a lot of text. And show the amount of ants needed for more layers to give a feeling of progression.
All in all, a solid job, if a little overtuned for a jam game.
