Thank you so much for the kind review! We appreciate it!
With the bananas, their current purpose is to add replay value as we didn't get enough time to implement a function for them. And the reason some may seem too high to get to is because of an action called the "ground pound jump". Straight after you perform a ground pound, jump and you will perform a jump a lot higher than normal. We understand that this move isn't very obvious in the game, which is unfortunate. :( But after the jam, we will keep updating the game to make it the best it can be!
Thanks for playing our game!
