I hope you're planning on making the base upgradeable! Would be cool to see it begin to look nicer and nicer as you progress through the game. Maybe have different paths (decorations or additions or w.e) to upgrade (which could give bonuses to certain types of units, or just overall bonuses; hp, damage, atk speed etc.) or maybe additional (or just bigger/different) bases to buy, possibly housing more raiders
