The protagonist is really cute! I enjoyed playing a sad banana. The monkeys are really well drawn, and the idle animation has such a cute little bob to it. The scrolling clouds up top are a really nice touch too.
A few things that would help the experience: I was hoping the controls could be mapped to WASD, and it would be great as a browser game so it's easier to jump into. There were a couple of moments where it wasn't clear how to interact with the environment such as climbing the vines, wasn't obvious, and I instinctively reached for the up arrow.
I also found myself waiting a beat for the camera to catch up to the protagonist. A snappier follow could really help the game feel more responsive.
Really charming little game overall — the character and world have a lot of personality.
