I was just asking about the console because I don't know the specifications of the Slim. I thought maybe it had slightly different hardware and the game is compatible with it but not Elite or older hardware. Just a guess, I don't know what could possibly cause some people to have no issues while the game is unplayable for others.
The developer seems to be ignoring my email, at least. No response in almost a week. You guys should send some to firstname.lastname@example.org
as it's the only way I can find to contact them.
