Malerouille is this meant to be a management sim or a tower defense game? You're doing a bit of both and I think you're going to have to sacrifice one for the other in order to proceed with adding depth to the game's mechanics. Tower defense is a strategy game and to facilitate the player being strategic they need to have very precise control, they need to be very sure of the outcome of their actions. Consequently these games tend to be highly abstract in order to reduce the cognitive load on the player, to let them focus on winning the game through strategy. Hence why in most tower defense games allies are either automatic turrets that you don't control you just place them, or just fodder you constantly stream into a meat grinder. In either case you don't give them orders or personally interact with them, you haven't got the time, you need to focus on what the enemy's doing how to counter it. Whereas in a management sim the focus is on the characters and dealing with their individuality, think Rimworld, you still have to fend off enemies but being raided is only 10% of the experience. 90% of your time is spent keeping your colonists fed, happy, healthy, entertained, choosing what to research and craft, deciding who to assign to what task, etc. Obviously Daggan isn't Rimworld but I think what's unique about Daggan is that you can breed your allies which could be really interesting to explore and I think it ought to be explored because breeding them makes the player immediately invested in them as characters. This isn't just cannon fodder #7 this is my son and that's my daughter and this is my wife and as the mayor of the town it behooves me to pay close attention to the local gene pool and to assess passing travelers for useful traits to add to it. In summary I want you to ask yourself this: Is this a game about fighting or fucking? Because you can have both but you need to pick your priority.
