Ok, I'll bite!

I think this odd cat shooting a bow golf game will suit your needs. Its really simple and quite fun (with a few bugs of course)

As a bonus a great buggy real life app is hosted by Adam Goucher. The Parking Calculalor is probably one of the buggiest apps I've ever seen and its the first thing I thought of when you posted your question. It's actually found on an airport website but has been hosted by Adam so you don't have to hit their prod site.

Spoiler alert! Don't read below if you want to hunt for bugs yourself :)

In about 10 mins in Catwithbowgolf I've found

1. you can shoot yourself off the board
   
2. you can shoot through the ground (and hit the target)
   
3. you can shoot your character through the small pieces of ground
   
4. you can shot your character infinitely up if you go far enough out of bounds
