Thanks for letting me know. I will look into this, but I suspect I already know what's going on. If I am correct, then this is the same issue that will be will be fixed in the near future, only it also applies to older versions of chrome. Sorry T_T
The game is also available for download on windows and linux (mac coming soon), hope you will still give it a try! If there are any other issues or you can't install for some reason let me know!
I am curious, what OS are you running?
