This game won't get ANY more updates (sad i know) probably some minor bug fixes but that's it, no new levels or plants or zombies.
There are some unavailable plants too at the time of writing this, might release them in the future, probably not?
Added 1 level that's just 4 fun introducing:
4 cut plants:
Brustoor - Shoots Piercing poisonous spikes
Magic shroom - shoots 3 cards and when tapped on releases magic
Kernel Pult - Lobs corn, butter or the cobtail
TwoPeater - they share the same 1 braincell
5 new zombie variants:
Hapi basic - just an angry basic but more annoying
Boxed bunch - releases 3 zombies when box is broken
Tophat basic - weaker conehead
Ghost Buckethead - goes through plants
Ender conehead - has a chance to teleport forwards
