Fun, even without audio. The art is nice and it was a challenge trying to get to enough apples without feeling impossible. (I've yet to get past the industrial age and really want to keep trying.)
If you ever get to add audio, I would suggest an apple sound effect as well as background music/running audio. If you go for running footsteps as the BGM, a realistic crunch would be great for the apple, though if you do music, a video game "get" sound effect would fit better. Congrats on making the deadline :)
