Great game! I'm going to keep playing it until I get on the scoreboard. One problem I noticed was that I would accidentally upgrade the wrong thing because the menu pops up instantly. But it's a wonderful game either way!
I upgraded the tongue length and damage a lot so I could just one shot everything across the entire screen. After that I kind of just sat next to the eggs and spam clicked everywhere. I've have only been able to tie my record trying this strategy again.
