I was also having an issue with the difficulty selection screen. I brute-forced my way into the game by clicking at the bottom left a bunch, but I was unable to find out the controls. Please reply to this comment once it is fixed so I can give it a rating!
hey sry for the late reply the game is a controller only and there is a bug where when you don't select your difficulty you can't get to the next scene because the slider value is 0 I am changing it so that the value = 1 from the start hope that helps and if you playing my game pls tell my if you could play it thx. ps Below I also have a diagram with the controls I hope it helps :)
