# 2020-01-13 (1.1): save high scores, shield power-up (which also changed some existing powerups due to how the pseudo-randomizer works), fancier title and game over screens, added sparkles, made an icon, fixed bug where you could use the speed powerup infinitely many times
# 2020-07-05 (1.2): made it so you can use any key or tap anywhere to jump; added "Fill window" and "Don't save high scores" options; added "Disable walls", "Show jump arcs", and "Change all powerups to..." to assist options
# 2020-07-08 (1.2.1): fixed a bug where "Full screen" would result in a temporarily blank screen in certain situations
# 2024-01-09 (1.3.1): made the background go all the way to the screen edge on newer iPhones; alt-enter now enters full screen; changed some stuff about spacing for the text around the game/manual/commentary
