the instructions are in the game menu :) THIS IS JUST A GAME THAT WORKS. I WAS PLANNING TO PUT EXTRA DETAILS, BUT I DON'T HAVE THE TIME ;-; The "hs" variable records the waves, not the kills :)
Thank you @TiltedHorizon for giving me feedback on my game (even though that was the one with extra details that i'm working on, but still thank you) Thank you to @bengames for the health bar. I used some of their code and adapted it to this game. Thank you to @aselley for being a good teacher :D
