I really love this entry! Its got fantastic graphics and sound with good level design that plays into the mechanics. I did find the lack of checkpoints to be extremely unforgiving in the later level where you had to bounce on top of enemies with blind jumps; The collision for bouncing on the enemies especially over the first pit caused a lot of deaths where the monkey's fall speed is extremely fast and doesn't seem to be clamped.
I really like that the tutorial is in the form of animated gameboys. The banna collectibles seem quite pointless and detracts from the game as there's no reason to explore these huge levels when a one hit death is extremely penalising.
The monkey's dance is nothing short of amazing!
Overall I could see this being a really great game if further developed.
