Nice work, it was very much on-theme!
I noticed the space in the level was a bit too tight to play properly, so I recommend opening up the level a bit and increasing player speed.
It might elevate the game a bit to introduce modifiers to player/enemy health/speed/damage/jump height etc, maybe negative ones are more likely the more cookies are risked and positive ones with less risk.
I tried out the linkdin shortcut and it worked... weird!
