PvZ 3 things to add and remove

Additions 

the threat icon: so it is easier for players to play against and a reason to add zombies that benefit from those threats

plant food and taco time

level and map creator

More plants and zombies

rarities (not plant levels)

remove/change

lives system

tutorials for literally everything

Idk if you can but stop spawning all the zombies on one lane

change the power ups to not be actual plants

honourable mentions

the option to swap grapes of wrath for a different ability

Give the base designing mechanic maybe give different buffs depending on what we pick
