It’s mostly the way it was created in the tutorial. I added some things. Most importantly, I added power-ups. Red en green blocks drop more interesting things than yellows.
I also added some awkward angle correction, that makes sure that the ball always has an angle greater than 20 degrees from the x-axis, to avoid tedious waiting on balls.
I’m sure it’s still riddled with bugs. Sorry about that in advance.
