It’s very unfortunate that you have this problem. The game works normally for me on multiple browsers so it is difficult for me to track down the problem. Are you able to share what browser you are using and can you check your browser’s developer console to see if there is any errors?
I tried the WebGL build through itch’s app and had the same problem as you. There was also multiple graphical glitches that gave us an excellent screenshot to put into our game’s description. Seems like itch app handles WebGL differently compared to web browsers.
I made a Windows build for the game so feel free to try it through the itch app. It should definitely work better compared to the WebGL build.
