I didn't have any flickering but I did have an issue on my first go where I ran out of dungeon and bunnies. It was only a few rooms and I still had 50+ seconds left on the clock when I'd cleared it. Subsequent runs were better.
Cheers for your comment RyanH82! :) Glad subsequent runs were better - yeah I had this issue too - if I had more time I'd have fixed it (and lots of other things xD)
