Beat it in like 30 min XD. What's impressive is that you made it all in a custom engine in less then 12 hours. Somehow, I can picture this as a speed runner game if you added more control on what pals you can get.
On the top of my head. Maybe before spawning you pop up two sprites like the 404 error and which ever the cannon hits that is the pal that spawns. I don't know if that will be more annoying or challenging later on with the auto clickers tho.
