Thank you! I will continue to develop it and make a full game.
1. Indeed in the future there will be different building paths with various types of turrets, defensive shields, research buildings and objectives that you will have to build and defend. The game will be a roguelike with story and ending in which each game will be different, with a game loop similar to FTL and Into The Breach.
2. In the beginning everything had more range and you could get through the game with only one type of turret reaching everywhere, it still happens with the sniper if you increase the attack speed a lot. It here is still a lot of balancing work to be done, maybe I should increase the range a little bit more but I want to make each turret fulfill a specific function, and that you have to place them in such a way that leave no open flanks to be effective, this will be more noticeable when I add different types of enemies and objectives to defend. Thanks a lot for feedback.
I abstracted the idea of “You are the gun” because I didn't want to do the first thing that comes to mind of literally being a gun that shoots, so I thought of a game concept that would give the feeling of “You are the weapon”. I thought that when you build the base around the core it would give the feeling that you were building a single weapon as a whole, I tried to make each turret serve a specific function, short, medium and long range and you would have to place them in a way that left no open flanks for the whole weapon to be effective, so it's not the typical tower defense where you place the weapons in a path. The UI is a quick placeholder for the prototype, when I continue developing the game I'm going to rework it. Thanks for the feedback!
