Curious, how much is there to do actually? I feel like I fr missed something when all I saw as an unlock was the door to get into the gun shop.
That's all that is in the game at the moment. the developer is working hard to add more. This is a very early stage of the game
4 enemies, each with an animation. The gun shop and what is between the cliff and left most passage way is what is available right now. The extra part of the house in not available as of this writing.
