the tower defense part is genuinely fun, placing units, building a comp, clearing waves, i actually like the strategy of it. problem is you dont EARN your units, you roll for them. its gacha. the meta units live on banners behind luck, and the banners run on fomo timers so youre pressured to roll now now now before the good one leaves. f2p you can grind currency to roll, sure, but a spender pulls the whole meta comp in an afternoon while youre farming a week praying rng smiles. the strategy game underneath deserves better than a slot machine bolted to the front of it. 2. fun to play, painful to progress fairly.
