Congratulations on your first game jam. I'm sorry to hear your first idea didn't work out, but at least you were able to deliver this one. Like you said, the game is basic, but it's solid. My only criticism is that incremental games usually have some sort of automation for the clicks later on, I wasn't able to find any on yours.
Apart from that it's a solid incremental game, and like others have said, it could turn into an educational game.
