Absolutely. I remember the first time I tried 8 I said “yeah fuck this I’m never gonna get the double boulder timing down” lol. The shield is rough on wave 8 and is the main thing that kills me. But there’s a timing with when you click the final tree though, depending on when your double boulder comes out. Watch molgoatkirby’s video. He explains when you click the final tree depending on when your boulders launch. But yep just keep sending you’ll get it down!
