Pretty good but I might possibly have found a bug. When you need to find 5 coins it started counting at 0. So when I found 5 coins the count showed 4. Thought maybe I needed to actually find 6 but I spent a long time trying to find it. Much longer than it took to find all the first five so I thought maybe that was a bug.
I let myself get caught so I could try again but having to do everything over again is a bit much. I got bored trying to get through the first maze again and gave up.
