I'll change the default sfx to medium. I did manage to add audio settings off, low, medium, high but forgot changing the default.
Thanks for the kind words regarding gameplay! I did use AI for most of that, telling it strictly how I wanted it and by providing examples of how I have written from scratch before with taking input from both gamepads and keyboard. Writing a platformer from scratch myself without AI assistance didn't work out great all the other times I tried. So I'll need to analyze the code and see what I can learn from it myself. Planning to do some manual refactoring when I have time. But then again a tiny change could totally break the feeling of a smooth gameplay. Thanks for playing and reviewing!
