hi. Sorry for the inconvinience. May I know what browser did you use? And are you using android or mac? You may request a refund on the payment page and I will send you a link for the game compatible with your device
I'm on a mac and I was using google chrome as instructed. I think I maybe figured it out, cookies have to be allowed otherwise it gets very buggy. So, don't worry about it. It's still incredibly slow, but at least it runs.
