I get it. It's even more frustrating when you play quad chimps and die on round 99 because your 400 alch doesn't throw "green stuff" on the grandmaster ninja, but instead throws it on one of your shinobis
I beat quad chimps before engi came out, so no op overclocks for my ninja, and I couldn't see the bloons underneath on round 98 since the MOAB class bloons are so fat
It took me 14 hours spread over 5 days to beat quad, but it was worth it because now I can flex my borders on noobs, oh wait, I forgot about the toilet paper
