If you're still stuck at level 14, you can grind easily by going into quick match, putting max bots in free for all with 50 kills on normal or easy difficulty.
Pausing the game while I'm jumping to give me inane advice is annoying. Also, how about some invincibility after getting hit so I don't lose 3 pigs on one line of traps.
