Good idea! I think the map could have been smaller, and it sometimes feels impossible to find the monkey. When you do find the monkey though, it's almost too easy to hit it 3 times.
If I could suggest anything, maybe make it easier to find the monkey but also make the monkey's movement become more erratic as you hit it? As is, when you find the monkey you can just walk behind it and hit it 3 times.
Regardless, I had fun with it!
