The art on the game is pretty stellar, I really admire it! Maybe some of the best I've seen in the game jam.
To be honest, I found the game a bit difficult to play for some of the reasons already mentioned - camera, foreground/background differentiation. Also, sometimes the apples don't respawn, making it impossible to continue.
That being said, I really admire the work that was put into this and possibly see what this game looks like in the future if you both choose to work on it!
