What a creative idea! There are so many incremental games where you start out constantly clicking, and as you buy upgrades to automate manual tasks, you don't have to click as much. Well in this game, the initial challenge is not merely "click a button over and over," but instead an actual skill-based task, that becomes gradually less challenging and less important as you buy upgrades. I hope other games will take inspiration from this.
The game's balance is awkward... it quickly goes from quite hard (at least when using a laptop trackpad instead of a mouse) to trivially easy, at which point there's not much left to do... except buy a couple of upgrades every few levels. I don't know if the number of levels is infinite, but I'm on level 21 and I haven't actually had to do anything except click "next level" for quite some time now, so I'm ready to give up and call it done.
But then, I don't expect good balance from a quick game-jam game, I expect innovation - and that, it's got.
