I wouldn't worry too much about it if you plan on continuing this game mostly has a download option. I find browser versions can sometime be fiddly, maybe just also add a downloadable version :)

Thanks again! I also found out that having hardware acceleration/graphics acceleration off in your browser can make the game completely unplayable :(
Just mentioning in case you did want to check it out (or I'll update the game files with downloadable stuff after jam anyway, so if you're still interested you can check out then too :))
