This game is pretty fun! Very simple and straight forward, so you could add some more stuff like: Medals, scoreboard, sounds, objects to interact with... the improvement-list is endless my friend.
You could always put that little redneck-guy beside the catapult and make him fire? Because it was kinda wierd that he was the hospitality-guy... I don't know! Maybe you could ad some clouds and stuff?
Anyways.... this is a small game with loads of opportunities! Btw, this is even better than your other games, though!
