summon banners. in a tower defense game. thats basically the whole review. you grind gems or you crack the wallet for whatever limited unit is meta this month, then the next banner powercreeps it and you do it all over again. everyone calls it strategy but the real strategy is did you pull the 5 star. the free units clear early content fine, ive done it, but every event and the entire endgame is a funnel pointing straight at the shop. gacha in a tower defense is still gacha. im not feeding robux into a slot machine with anime skins on it. 1.
