Fun game! I don't usually finish games but this one I did, it was fun and challenging just in the right level.
I like the design that you can't go back, which means your jumps have consequences and to get a perfect score you have to be precise, but you're not punished hard for missing the best jumps since you can collect monkeys from the bottom aswell. Time challenge was just about right too, I finished with 56 monkeys and 2 seconds left on the clock .
Loved it! :)
