Thank you so much for the feedback. Yeah, I actually had the code for creating entirely random waves, but I forgot to add it T . T (I literally forgot one single line of code to add it properly). The difficulty is supposed to increase for each wave, but maybe it's a little slow. I found that people who tested it for the first time found it too difficult. Meanwhile, people testing for the second or third time found it too easy, so it was hard to balance it out. Maybe version 2.0 gets to be more balanced. :D
