I liked the art of the apple, as well as the limitation of only being able to move forward while jumping. The first level gives you not nearly enough time to figure out what you're doing before you lose - I didn't even have time to notice the timer the first time. It took several tries for me to realise that you had to both collect all the photons and reach the exit. The frequent retries made the single resetting song wear on me quickly.
An interesting idea that could use some more polishing and balance. Good work!
