speaking of which, I tried reproducing old strat that uses gloom shroom in front column (that works by making use of the fact that ducky tube zombies don't start biting wide pumpkin until they walk into pool. then I'd do all that stuff like stalling final zombie on first wave (sigh, if that cheese were useful in this game, being able to keep low dps ranged zombie in 2nd column indefinitely (unlike with basketball catapult zombie which drives forward after a while) would make it even more convenient) to build up sun for winter melon support, then take my time adding pumpkins to other less critical stuff, replace sunflowers with marigold, etc.) which doesn't suit this game in all sorts of ways
