I like the concept,
I didn't realize I had to left/right click to choose upgrades (maybe an in-game indication would be nice)
But it's just enough to keep you engaged, I found myself playing multiple rounds
I'd say maybe have chickens collected and go to the same place and then you decide what to spend them on. Rather than collecting 2 chickens for left/right and then deciding oh I would love to move these chickens but now I can't.
This might also not be needed, but maybe adding some tradeoff for destroying eggs? so clicking on them by mistake is the whole concept, but maybe there would be a reason to destroy them so a chance of getting something out of them, so you wouldn't go around destroying all eggs, but if you have enough you would wanna consider reducing the number of eggs around for the chance of something good happening (just a thought)
But good job!
