Even though the game's original design is to be a strategic game (I think?). I quite enjoy building the tower high and watching it destroy the monsters like a cookie clicker kind of game. The chill music and the ticking sound is a nice vibe in my opinion and I wouldn't mind playing it more as if it's a cookie clicker with bigger numbers and more upgrades to the turrets and big enemies.
I also quite like the damage ui text too. Simple but effective.
