You crammed a lot of pinball into a tiny screen! I like the little touches like the drop shadow behind the text, and the way the "Play" button has an animated fill when you hover with the mouse. And it seems like there is a lot of nuance to the scoring system!
I did find it a little odd that the game sort of played itself - but I'm not sure if that is standard in a lot of pinball games! After I hit the ball, it bounced around on the left side for a few minutes, racking up 42k points and upgrading twice without any input from me.
