I liked it
It certainly wasn't perfect, but it was in a way touching, and very beautiful.
There were a few things I noticed however. They were only little barely un-noticeable things.
Firstly, in most scenes, the bird would have high levels of shading and the jungle creature didn't. This is ok if it was consistent as you can use it to show something about your characters, but in some shots the roles were reversed, or both characters had shading. This ended up annoying me.
Also, some of the movement wasn't timed quite the way I expected it. In a few scenes the jungle man gorilla thing seemed to float and glide instead of actually leaping. This sometimes acted in reverse, especially when the flower was growing. It was the sort of scene that deserved a slow cinematic.
These few things subtracted from the overall quality of the movie, but it was still great, and I'd love to see more.
P.S Can't wait for the game jam!
