I like all of the feed back. I want you to be more Monkey Mode. I like very precise like movement which is why I have some levels like that. Not so sure any of them should be required if there's a final version. (The final version would have a world map with levels to select and a lot of new gimmicks).
There're Gorillas, they see monkey they run at monkey. :) (Maybe could add a new Gorilla that runs away when you enter Monkey Mode).
The hitbox of the banana? Yeah, I could see how to make it better.
