Idea: like pvz there could be special things that need 1 thing to be placed first (example winter melon in pvz 1 or cob cannon from pvz 1 which needs 4 plants or just a idea i has of kinda mixing things like placing icicle baby on cube of meat to make cube baby) and that you would get them from the thing at the end of a level (except for boss i guess since thats a shop) also a good idea would be to perhaps nerf the stone poop enemys (i forgor what they are called) they can easily destroy a row of stuff if you dont got something ready for them (examples: red/blue candle or i think the thing called red maw)
