Rework For Adventure Mode

An idea for make adventure mode a more complete and not so long mode could be bring back the old Worldmaps with just 10 levels per world in those 10 levels you encounter all the zombies and isn't cutted in 2 parts.

After doing that Every levels would be more longer and A bit more harder for still having the same quality.

every time you clear the level 10 in a world you unlock the Endless Zone and 3 stars would be available to get in all levels in that world, and those are the challenges we already know, Don't Let Zombies Trample the flowers, Don't Spend X Amount of Sun, Don't have more than X plants, Etc.

Clearing those objectives would give you a star (collect the needed amount to access to other words) 

Also the Key System would be something for player selection, you get X Amount of keys to unlock a Brain buster Door to get Upgrades, Plants and A guaranteed star for playing those 3 Levels (the levels are just like the minigames in PvZ1 and you got plants and upgrades to playing them) 

The gargantuar node would be located in the final day (day 10) in every world being a special delivery level more challenging (Gargantuars also would appear 1 level earlier (Day 9) for search a way to defeat him with your own defenses 

The Dr. Zomboss Node would be Hidden in the Worlmap and you would need all the stars (From the Original Path and not the Brain buster doors) from the world to unlock it and being able to Fight Dr. Zomboss 

This would make the adventure mode more complete and having a reason to replay levels to get stars (The Treasure Yeti Launchbox can contain and Amount of 3-5 Keys for being able to unlock the doors earlier
