Sorry, my comment wasn't very clear. On the app page within the playstore, if you scroll to the bottom and read the reviews you'll see the developer has replied to say a fix will be released today. I'm yet to see it though.

Wow that brings back memories! I used to play this in the back of the car with a torch! Lost my GB years ago.

Thanks for bringing back good memories!

There's a fix the dev has just released. See reviews section on the app. He said it'll take a few hours to show in the playstore.
