This is the one i have played in the past and liked and which inspired my to make this game. I want to make a similar game but in my own way
Another game i looked at which went into a lot more detail was Castle storm. It had 2 elements of being able to build you own castle and another to use a catapult to destroy the enemies.
Concept
this is a quick sketch of ideas i had before detailing them on the second image where i showed the layout of the game.
