I'm not sure how the criteria works for getting points for upgrading. It seems you get them only when you beat your top score but then how many do you get? It's not explained. And what do hats even do?
I wont call it a flappy-clone (like someone did below) because that game didn't invent the idea and I've always prefered versions, like this, where you can hold the button down so you don't have to click repeatedly like it's going out of fashion, which it did. I think I would like it if you just got given your points to spend on upgrades after every flight.
