Hi! So sorry this issue is happening for you.
I've just updated the game file and tweaked a couple of the export settings - so it's worth trying again, although I can't make any guarantees! I'd also recommend trying the game on a couple different browsers? I've tested it on Firefox and it's working on my machine.
I've said it in a post lower down, and in the description, but this is really just to be treated as a 'demo' for now - the download version is available on my Patreon, but if you're on Windows, I also ran off a version optimized for lower-spec PCs (and those running older versions of Windows) which you can download from Mega here: https://mega.nz/folder/zLZigYjZ#Ur4_aYQOzE5KvbTzDhgS-A
Outside of that, if none of the above works, all I can suggest is that you hold off for the next update, where I'll be putting more time into an optimized browser based version, but there's only so many hours in the day, I'm only able to work on the game part time and right now my focus is on getting the next update finished - aiming for the end of this month, all being well. :)
