Very good game, but short...
Did you think about add generating maps in game?

If it’s interesting, I would suggest the following algorithm: first draw the bullet’s flight curve (with random bends), and then, relative to it, step back on the sides by 50-100 px and draw up a path map, as they did in Worms, with its own curvatures. Well, the number of bounces = the number of kinks along the bullet’s path.
A potentially useful algorithm for your future work
