Cool. Despite being simple, the art portrays a rich landscape and the riddle at the bridge was pretty clever. (Fun fact you may already know: in reality neither the fruit nor color came first - orange was the name of the fruit tree itself and eventually the name transferred to the fruit.)
For some reason it took me several dozen times to reach the bridge without falling or hitting enemies despite the straightforward mechanics, though I can't tell how much was the game being hard and how much was me. I would suggest getting rid of the enemy directly under the second floating platform, though. You can't see it from that high, so I couldn't avoid falling on it.
My final suggestion is to add a jump sound effect. That was what I was told when I made my first platformer and it really improves the game. That and an attack sound effect when you hit the enemy.
