I don't know whether it happens app or the website. The web version doesn't run, so I guess the former (since other games on the site work fine)? I just tried the web build on my computer and it works just as intended. I don't know how to open the browser console (unless it's the default one rather than one specific to this site). The game is made with Gamemaker, here's a link to the broken version: https://tolkki.itch.io/bonehead-v0394
