Oh no, this is the first I've heard of someone with this problem. What platform are you playing on? I've made it available in browser, windows (download), and linux (download). Try in Chrome or Firefox, if you still have issues then the downloaded version should actually be the most stable.
Running in Firefox on MacOS. Works in Safari, but with glitched out audio.
Made it to the top of the pyramid, but then got stuck in a death loop after falling of the left side. However, from what I have played it was a fun game. : )
